STOLEN OFF WIKIPEDIA, BUT THAT DOESN'T MATTER DOES IT? Also, no fucking trolling. I'm not as forgiving as the rest of the staff here. Technical specifications The PlayStation Portable was designed by Shin'ichi Ogasawara (小笠原伸一) for the Sony Computer Entertainment subsidiary of Sony Corporation. Early models were made in Japan but in order to cut costs, Sony has farmed out PlayStation Portable production to non-Japanese manufacturers, mainly in China. The unit measures 170 mm (6.7 inches) in length, 74 mm (2.9 inches) in width, and 23 mm (0.9 inches) in depth, and has a mass of 280 grams (a weight of 0.62 lb) including the battery. The Samsung (previously Sharp) branded TFT LCD screen measures 110 mm (4.3 in) diagonal with a 16:9 ratio and a 480×272 pixel resolution capable of 16.77 million colors. It has four possible brightness settings, the brightest of which is disabled in the older firmware versions unless on A/C power. The PlayStation Portable's main microprocessor is a multifunction device named "Allegrex" that includes a 32-bit MIPS32 R4k-based CPU, a Floating Point Unit, and a Vector Floating Point Unit. Additionally, there is a processor block known as "Media Engine" that contains another 32-bit MIPS32 R4k-base CPU, hardware for multimedia decoding (such as H.264), and a programmable DSP dubbed "Virtual Mobile Engine". The secondary CPU present in the Media Engine is functionally equivalent to the primary CPU save for a lack of a VPU. The MIPS CPU cores are globally clocked between 1 and 333 MHz. During the 2005 GDC, Sony revealed that it had capped the PlayStation Portable's CPU clock speed at 222 MHz for licensed software. Its reasons for doing so are unknown, but are the subject of some speculation. Various homebrew tools enable users to operate at 333 MHz, generally leading to a higher frame rate at the expense of battery life. On June 22, 2007, Sony Computer Entertainment confirmed that the firmware version 3.50 does in fact remove this restriction and allows future games to run at the full 333 MHz speed. It does not affect already-released games.[17] The system has 32 MiB main RAM and 4 MiB embedded DRAM. The 4 MiB of eDRAM consists of 2MiB dedicated to the Graphics Unit and 2MB dedicated to the Media Engine secondary processor. There is no memory management unit for either CPU. No evidence of a TLB has been found. The co processor that normally manages the TLB-based MMU seems to be a custom effort by Sony and has no integrated memory. Both CPUs contain 16KiB of two-way set associative instruction cache and data cache respectively. There is additionally 16KiB of scratchpad RAM which, while faster than main RAM, is not nearly as fast as the integrated cache. The 166 MHz graphics chip has 2 MiB embedded memory and through its 512 bit interface provides hardware polygon and NURBS rendering, hardware directional lighting, clipping, environment projection and texture mapping, texture compression and tessellation, fogging, alpha blending, depth and stencil tests, vertex blending for morphing effects, and dithering, all in 16 or 24 bit color. The graphics chip also handles image output. Specifications state that the PlayStation Portable is capable of rendering 33 million flat-shaded polygons per second, with a 664 million pixel per second fill rate.[18] Optical drive The PlayStation Portable uses a drive compatible with Sony's proprietary Universal Media Disc format. Use of the drive increases battery drain by approximately 10% and the system has been criticized for having very slow data transfer speeds, translating into load times of more than 2 minutes in total for some games. However this has been improved with the redesigned PSP as it now has a longer battery life and faster loading times.[citation needed] Controls Despite its movie and music playback capabilities, the PlayStation Portable has primarily gaming-oriented controls (as opposed to the controls typical to television remotes or MP3 players): two shoulder buttons, the PlayStation face buttons (Triangle, This image is a candidate for speedy deletion. It will be deleted after Sunday, 21 October 2007., X, Square), start and select buttons, a digital 4-directional pad, and an analog nub. There is also a row of secondary controls along the underside of the screen, for controlling volume, music settings (either switching the audio off and on in games or selecting different equalizer presets), screen brightness, and a "Home" button for accessing the system's main menu. Battery life PlayStation Portable's default battery life varies widely depending on application from less than 3 hours while accessing a wireless network and having screen brightness on its highest setting to more than 11 hours during MP3 playback with the screen turned off.[19] An extended-life 2200 mAh battery will increase this by approximately 20%. A sleep mode is also available that uses minimal battery power to keep the system's RAM active, allowing for "instant on" functionality. A system in sleep mode (with a fully-charged battery) has been shown to lose an average of only 1% battery life per 24-hour period. At E3 2007, new information about the "SLIM PSP" was released, including news that the new PSP will have improved battery life. This new PSP will use a thinner battery, its standard having a capacity of 2200 mAh vs 1800 of the original PSP. However, that information turned out to be false, as the new PSP, now known as the PSP Slim & Lite, actually uses a smaller capacity battery of 1200 mAh. Overall, the PSP Slim & Lite has the same battery life as the original console, due to the lower power consumption. Original batteries will be compatible with this new PSP, however, the battery cover will not be able to fit over the battery but Sony is reportedly working on a workaround. Interface The PlayStation Portable's main menu interface is the "XrossMediaBar" (XMB) used by recent Sony TVs, the PSX (DVR) hardware, and the PlayStation 3. It consists of a horizontal sequence of icons, in this case Settings, Photo, Music, Video, Game, and Network, which show a vertical sequence of sub-icons when highlighted. The XMB allows the user to adjust settings, connect the device to a PC (via USB), connect to and browse the Internet, and play video, audio, and games. The XMB may be accessed at any time in a game by pressing the Home button, but the PSP must exit the currently running game due to memory limitations. The PSP's default background color changes depending on the current month of the year. The user may also manually set the color or specify a background image from a connected Memory Stick (with firmware version 2.00+).[20] Firmware 3.70 and higher include the Custom Theme feature, which lets a user change everything in the interface (Icons, Background). Currently, there are 10 official themes: Lemmings, Wipeout, "Cookies," "Pink," and 6 different themes based off of the game Pursuit Force. |

So what does this wall of text mean? It means the PSP is a device capable of many nifty things. "Proper" uses for a PSP: Music player Watch movies on it (they have to be on UMD disc, or they can be on your memory stick, but they have to be in MP4 format. also, LOLPORTABLEPORN) View pictures on it Play games on it Use it for the internets by leeching off peoples wifi connections Interact with the PS3 somehow The best reason to have a PSP is the ability to downgrade from official firmware to install custom firmware. With that, you can do a whole lot more, although that most likely means you'll be pirating lots of stuff. I'll post more later. I'm gonna pick me up a copy of Castlevania: Dracula X. FUCK YEAH. |

Forget official firmware, I have the unofficial one which is better. I even have the Pandora's Key which allows me to downgrade the firmware into any PSP. Of course, I don't own one anymore but planning to get another one later. Disgaea: Afternoon of Darkness is coming out next month. Can't wait. |

Yep. If someone takes the PSP from you and uploads the official fireware, karma, that's all you have to say. K-A-R-M-A |
