The Xbox 360 is the successor to Microsoft's Xbox video game console, developed in co-operation with IBM, ATI, Samsung and SiS. Information on the console first came through viral marketing campaigns and it was officially unveiled on MTV on May 12, 2005, with detailed launch and game information divulged later that month at the prominent Electronic Entertainment Expo. The Xbox 360 is the first console to have a simultaneous launch across the three major regions, and the first to provide wireless controller support at launch. The console sold out completely at release and has since sold 6 million consoles wordwide. It is the first console to be released in the seventh generation of game consoles and will compete against Sony's PlayStation 3 and Nintendo's Wii. The system contains a 3.2 Ghz tri-core PowerPC based CPU and a 500 Mhz GPU. Its Xbox Live service allows gamers to compete online, download games and additional content. Microsoft believes that its push towards high-definition gaming, year-early head start and its Xbox Live online gaming service will help the console be successful.

The console's graphical user interface is the Xbox 360 Dashboard; a tabbed interface that features four "Blades". It can be launched automatically when the console boots up without a disc, or when the disc tray is ejected; or the user may choose to launch a game automatically if a disc is inserted. A simplified version of it can also be accessed at any time via the Xbox Guide button on the gamepad. This simplified version shows the user's gamercard, Xbox Live messages and friends list. It also allows for personal and music settings, in addition to voice or video chats.
The Base Kernel Version of the dashboard is 2.0.1888, the first major update, version, 2.0.2858, was released on June 13, 2006.[2] This version gave users the option to resume DVD playback from where it was last stopped as well as the option to boot to either a disc or the dashboard. New slideshow options were added for Photo Viewing, which can save folder layout between sessions. Xbox Live Marketplace was reorganized and users can now have concurrent downloads, allowing multiple downloads as background tasks. THIS CONSOLE IS CRAP!!!!!!!!!!!!!
The current dashboard version, 2.0.4532.0, was released on October 31, 2006. [3] It allows the Xbox 360 to output video at 1080p and installs support for Zune and the upcoming external HD DVD drive attachment. WMV files can be streamed from a computer through the use of Windows Media Connect or connected USB device. Windows Media Player 11 was added as a supported streaming program. Xbox Live Arcade can now be set to automatically download trial versions of any newly released titles. Cosmetic changes to the dashboard were also made.
Microsoft XNA
Microsoft XNA is a set of tools and technologies which include XNA Studio which provides versions of key production tools such as asset management, defect tracking, project automation and work lists. These tools are designed to work together to automate common development tasks and present interfaces tailored to the different functions within the team. John Carmack stated at QuakeCon 2005 that the Xbox 360 has "the best development environment I've seen on a console".[4] Microsoft XNA also includes other components such as the XNA Framework and XNA Build. Anyone can develop a game using XNA Game Studio Express, an IDE for homebrew developers that will be fully available free of charge during the 2006 holiday period[5] with an initial beta released on August 30, 2006. A second, near feature complete beta version was released on November 1, 2006.[6] It targets the XNA Framework only to provide managed content and for a $99 USD yearly subscription fee users can join a "creators club" which lets them share their content with others.
Backward compatibility
- For more details on this topic, see List of Xbox games compatible with Xbox 360.
Backward compatibility is achieved through software emulation of the original Xbox. Emulated games offer graphical enhancements because they are rendered in 720p, 1080i, or 1080p (available via Xbox live update)[3] resolution with anti-aliasing enabled rather than the Xbox standard of 480p. Some games also benefit from an improvement in the rendered draw distance, possibly due to the system's greater memory bandwidth. However there are also games that do not perform well in emulation; these often exhibit a lower framerate on the Xbox 360.[7] A hard drive and the downloading of an emulation profile is needed in order to play original Xbox games. Updated emulation profiles can be obtained through Xbox Live, by burning a CD with profiles downloaded from Xbox.com, or by ordering an update disc from Microsoft.[8] The full list of backward-compatible games is maintained at Xbox.com. Although the current U.S. list includes nearly 300 games, fewer titles are backward compatible in European and Japanese markets.[9] Microsoft has stated that they intend to release more emulation profiles as they become available, with a goal of making the entire Xbox library playable on the Xbox 360. They have since made multiple statements indicating that this may never be complete, and the rate of updates to the backwards compatibility list is in line with this stated attitude.[10]
Game library
The Xbox 360 launched with a number of games. One such, Call of Duty 2 was the console's best selling game for 2005, selling over a million copies [11]. Only two other games have sold this amount, Ghost Recon Advanced Warfighter[12] and The Elder Scrolls IV: Oblivion.[13] Second-party developer Rare had two games at launch: Perfect Dark Zero, which was Rare's first major commercial success after Microsoft's acquisition of them and was believed by some to be the console's flagship launch title; and the RPG Kameo: Elements of Power. Only six games were initially offered in Japan and eagerly anticipated titles like Dead or Alive 4 and [eM] -eNCHANT arM- were not released until several weeks after launch. Games more suitable to the region are planned or have since been release, such as Chromehounds, Ninety-Nine Nights, or Phantasy Star Universe. Microsoft backed Mistwalker currently has three Japanese style games in development, Lost Odyssey , Cry On and Blue Dragon. On October 19, 2006 limited edition Blue Dragon bundles sold out of pre-orders on the first day in Japan. With over 10,000 units, the pack priced at JP¥29,800 includes the core Xbox 360 system with a retail Blue Dragon, along with table calendar, Blue Dragon faceplate, and five miniature character figures.
E3 2006 was the first large scale show after the console's launch and had the first trailer for Halo 3, the sequel to the original Xbox's best selling game. Fable 2, a sequel to the Xbox's best selling RPG was also shown along with Alan Wake, Mass Effect and Too Human. Bill Gates spoke of plans to integrate several Microsoft services into one entity with Live Anywhere. This service will allow multiplayer games and communication possible between Xbox 360 and the upcoming Windows Vista operating system for the PC. Shadowrun was the first game announced to be compatible with Live Anywhere. Several games originally released on PC have also been released on the Xbox 360, such as F.E.A.R. or Quake 4. Grand Theft Auto IV was shown and will be the first title in the series to be released for the Xbox 360 the same day as its PlayStation counterpart. At X06 Microsoft announced new titles, along with information of future releasing titles. Splinter Cell Conviction, set to release after Splinter Cell Double Agent was announced to be exclusive to the Xbox 360, as were Bioshock and Banjo-Kazooie 3. At the event Halo Wars was also announced, along with an Untitled Halo Project. Microsoft is publishing sequels to some of its more successful franchises that were released on the original Xbox, such as Forza Motorsport 2, Project Gotham Racing 3 & 4, and Fuzion Frenzy 2. In addition to sequels, they have published original games based off of new IPs such as Viva Piñata and Gears of War.
Hardware
[edit] Central processing unit
The Xbox 360 takes a new approach to hardware compared to its predecessor. The CPU, named Xenon, is a custom triple-core PowerPC-based design by IBM. The CPU emphasizes high floating point performance through multiple FPU and SIMD vector processing units in each core. It has a theoretical peak performance of 115.2 gigaflops and is capable of 9.6 billion dot products per second. Each core of the CPU is simultaneous multithreading capable and clocked at 3.2 gigahertz. However, to reduce CPU die size, complexity, cost, and power demands, the processor uses in-order execution in contrast to the Intel Coppermine128-based Mobile Celeron used in Xbox which used more robust out-of-order execution. The chip currently uses a 90 nm process, although a 65 nm process SOI revision is planned for 2007.[14] A 21.6 GB/s front side bus, aggregated 10.8 GB/s upstream and downstream, connects Xenon with the graphics processor/northbridge. Xenon is equipped with a 1 MiB Level 2 cache on-die running at half CPU clock speed. This cache is shared amongst the three CPU cores.[15] The CPU also contains ROM storing Microsoft private encrypted keys, used to decrypt game data. Heat sinks are implemented to cool the CPU, the heat sink is composed of aluminum fins with a copper base heat pipes. The heat sink is cooled by two 60 millimeter fans at the back of the console.
Graphics processing unit
While the first Xbox's graphics processing unit was produced by NVIDIA, the Xbox 360 uses a chip designed by ATI called Xenos. The chip was developed under the names "C1" and "R500".[16] Xenos contains 48 unified shader units, which are capable of both vertex and pixel shading operations. This is in contrast to older graphics processor designs which utilize separate specialized units for these tasks. The GPU package contains two separate silicon dies, each on a 90 nm chip with a clock speed of 500 Mhz. The GPU proper, manufactured by TSMC and a daughter-die, manufactured by NEC, containing 10 MB eDRAM. Thanks to the daughter die, the Xenos can do 4x FSAA, z-buffering, and alpha blending with no appreciable performance penalty on the GPU[17]. The GPU also houses additional capabilities typically separated into a motherboard chipset in PC systems. A heat sink is also implemented to cool the GPU, it is made of aluminum and is wider and shorter than the CPU heat sink.[18]
Memory and system bandwidth
The console features 512 MB of 700 megahertz GDDR3 RAM on a 128-bit bus. The memory is shared by the CPU and the GPU via the unified memory architecture. This memory is produced by either Samsung or Infineon Technologies.
The Xbox 360 has an extensive amount of bandwidth in comparison to its competition[19]; however this statistic includes the eDram logic to memory bandwidth, and not internal CPU bandwidths. The eDram internal logic to its internal memory bandwidth is 256 GB/s. The high bandwidth is used primarily for z-buffering, alpha blending, and antialiasing; it saves time and space on the GPU die. Between the eDram die and the GPU data is transferred at 32 GB/s. [20] The memory interface bus has a bandwidth of 22.40 GB/s and the southbridge a bandwidth of 1 GB/s.
Audio and video
All games made for the Xbox 360 are required to support at least six channel Dolby Digital surround sound. Over 256 audio-channels and 320 independent decompression-channels using 32-bit processing for audio, with support for 48 kHz 16-bit sound. Sound files for games are encoded using Microsoft's XMA audio format. An MPEG-2 decoder is included for DVD video playback. VC-1 or WMV is used for streaming video and other video is compressed using VC-1 at non-HD NTSC and PAL resolutions or WMV HD. Unlike the original Xbox, voice communication is handled by the console, not by the game code, allowing for cross-game communication. There is no voice echo to game players on the same console; voice goes only to remote consoles. Even though there are no digital-outputs such as DVI or HDMI, a wide array of standard and HDTV resolutions, up to 1920×1080 in progressive mode (after fall software upgrade),[3] are supported by the console hardware.[21]
Storage
The Xbox 360 is equipped with a 12x DVD drive, capable of a maximum read rate of 16.0 MB/s. Games are stored on standard dual-layered-DVD-ROMs with 7 GB of usable space available for game content. The option to apply a regional lockout to games is available to publishers, although DVD region codes are always enforced. Microsoft has implemented methods to prevent hacking through the drive. Later drive models have the external debug triggering removed and black hard glue added to cover all the chip and controller pins.[22] The drive is able to read both DVD±R and DVD±RW in addition to being able to play DVD-Video out of the box, unlike its predecessor which required the purchase of an add-on remote. The system is also capable of playing standard CDs along with CD-R/RW, CD-DA, CD-ROM XA, CD-Extra, WMA-CD, MP3-CD, and JPEG Photo CD.[23] Some users reported problems with the disc drive, as when a user changes the consoles orientation, the inserted disc may brush against the drive's pickup-assembly and incur scratches to it. [24]
Announced at CES 2006 and first publicly shown at E3 2006, an external HD-DVD drive is set to release in North America on November 7th for $199.99.[25] It will be released November 17, 2006 in Japan[26] for ¥19,800. In Europe, the HD DVD drive will be released for €199.99/£129.99 in the U.K., France, and Germany.[27] For a limited time, the HD DVD drive will be bundled with an Xbox 360 Universal Media Remote, as well as an HD DVD copy of Peter Jackson's King Kong.[27] The drive will play HD DVD movies, although all Xbox 360 games will remain on the DVD format.[28] Microsoft has no plans to include an internal HD DVD player in future Xbox 360 designs.[29] The external drive connects to the Xbox 360 via USB and contains two integrated USB ports on the rear.
The Premium configuration of the system comes with an external hard drive and it is optional to separately purchase one for the Core. The detachable hard drive has a storage capacity of 20 GBs and is not required for standard games. The 2.5" drive is connected through a SATA interface and the drive spins at 5400 rpm.
Components and accessories
Xbox 360 also has a built-in 1000BASE-TX RJ45 ethernet port, suitable for connecting to Xbox Live, and three USB ports.[23]
Up to four controllers are supported by the Xbox 360, in either wired or wireless forms. The wired version of the controller can also be used as PC Game-pad because it uses a USB connection, directly connected to the controller; the Wireless controller cannot because it uses a wireless signal. A wireless receiver set to be released in 2007 will plug into the PC allowing wireless Xbox 360 accessories to be used on the PC. An optional wireless force feedback racing wheel for racing games will be available on November 1, 2006.
The Xbox 360 can connect to Xbox Live through an optional wireless network adapter on a home network through a wireless router. The Universal Media Remote can be used to control several functions of the console, including the Windows Media Center functions if connected to the network. Various other components for the console exist, such as decorative faceplates to change the physical appears of the console, wired or wireless headsets for communication over Xbox Live, and an Xbox 360 branded webcam called Xbox Live Vision Camera.
[edit] Miscellaneous
- See also: Xbox 360 technical problems
The Xbox 360 is similar in form factor to its predecessor. It is slightly slimmer in every dimension, the Xbox 360 is white and slightly concave, whereas the original Xbox was black and noticeably convex. The Xbox 360 has a weight of 3.5 kg (7.7 lb), about 350 grams lighter than the original Xbox. The console uses a 5 amp / 100-120 V A/C input and D/C output of 203W external power supply. Saving in size and weight, the power supply by itself displaces 1300 cubic centimeters.[30]
Much like modern operating systems, the Xbox 360 displays a "Screen of Death" if it encounters a serious error. In addition, the "ring of light" display on the front of the console itself changes from green to red, the amount of sectors illuminated informing a user what category the error falls into. In September 2006, Microsoft released a statement saying that they will waive the cost for repairs on all Xbox 360 consoles made before January 1, 2006, and refund any fees already paid. [31] When an Xbox 360 disc is started in a DVD player or PC DVD drive, a small clip will play and contain the message "To play this disc, put it in an Xbox 360 console."
