{WIP} More about the PS2 components...
#1
-- ***** I'M EDITING THIS POST IN REAL TIME! FOR NEW USERS, PLEASE REFRESH THE PAGE ALL 5 MINUTES ***** --

Are you sure you know 100% of your PS2? Hmm I'm not really so sure ... Let's see what she has under the hood.

The PS2 User Guide !

SUMMARY:

Index


Synopsis


First, the PS2, by Sony Computer Entertainment, was released March 4, 2000 in Japan. She will be released later in North America (NTSC) and Europe (PAL) on October 26 and November 24 of the same year.

It was sold about 160 million units. The most played game was Gran Theft Auto: San Andreas (not surprisingly).

There was 2 models of the PS2: the Flat and the Slimline. The slimline is 5 times more slime than the fat. The slimline don't have integrated power supply (slimline have adapter 8,5v), like the PSOne and other things that "deflate" the PS2. Note that there is no calibration of the CD, as there is no case, in contrast to the fat PS2 which is provided with a motor and a calibrator for centering the CD. Okay, I admit, this is not true. But the fact that there is no longer have CD case there is something in deflation.
Already, the PS2 was very powerful for its time, because being a console, its processors and its technology is very advanced for a year like 2002.

Anyway, there was 4 evolutions of the PS2: V14 (SCPH-7500X), V15 (SCPH-7700X), V16 (SCPH-7900X) and V17 (SCPH-9000X).

Well, let's see some hardware !

Bwaaa! I was forced to remove it from the motherboard with a knife, it has bent ... Not the knife, but the processor when hitting the ground so he was thrown away! Anyway, there is some things that pop-up when I was removing... I don't know what, maybe some glue Glare Also, it's dimensions are 4,2*4,2 cm, like a small key or a tiny webcam

Description


At one time, GS and EE processors of the PS2 were both together in a single processor.
[Image: CXD9833GB.png]

EE, or EmotionEngine, has been created with the cooperation of Sony and Toshiba, in 1999. This is a 64-bits processor. The EE is a Very-Large-Scale Integration (VLSI) processor that allow to place more than 100.000 components on the same chip. There is 8 cores on the same IHS (Integrated Heat Spreader) which each have a specific task. The processor is closely linked to the first VPU, VPU0. They are responsible for the interpretation of the code and the high-level calculation. The second VPU, VPU1 is devoted to the geometric transformation and lighting and works independently in parallel to the processor. The VPU0, when not used, can also be used for geometric transformations (polygons). [Thanks to Wikipedia]

The main processor is a RISC processor double core, superscalar, in-order. It implements the MIPS-III instructions and a large part of the MIPS-IV. The core MIPS is based on two ALU and FPU. The ALU is 64 bits but the FPU is 32 bits.

The communication between the Emotion Engine and RAM occurs through two channels RDRAM and the memory controller that interfaces with the internal data bus. Each channel is 16 bits wide and operates at 400 MHz. Combined, the two channels reach a maximum theoretical bandwidth of 3.2 GB / s, about 33% more than the internal bus. This is why the memory controller transmits the data sent by the DRDRam chains if additional bandwidth can be used by the CPU.

The Emotion Engine has 540 contacts in ball grid array. Also, the first EE CPU was clocked at 294 MHz, and finally 300 MHz for the newer systems.

    • VU1 typically used for polygon transformations, lighting and other visual based calculations (Texture matrix able for 2 coordinates (UV/ST))
      • Parallel: Results of VU0/FPU sent as another display list via MFIFO (E.G. complex characters/vehicles/etc.)
      • Serial: Results of VU0/FPU sent to VU1 (via 3 methods) and can act as an optional geometry pre-processor that does all base work to update the scene every frame (E.G. camera, perspective, boning and laws of movement such as animations or physics)

The Graphics Synthesizer


GPU of the PS2. What could I say? Lots of things!

First, the frequency of the GPU has never been changed. But there still a difference between the Fat version and the Slim version : in the Fat, the GPU is cooled by one heatsink separated of the one of the CPU. Not in the Slim, where the GPU and CPU use the same heatsink. But instead of be cooled by a air flow (Fat), the heatsink of the Slim is cooled by a direct air flow from a fan.

Description


There is not really information about the GS. It is simply a graphics processor with 4 MB of onboard memory. So, in view of the circumstances, the only information available in the following paragraph.

Audio


The audio of the PS2 is relatively efficient because it can go up to Dolby Digital 5.1. Here too, there is no lots of things to say.....





...come later !

My slim SCPH-90006 does come with an integrated PSU. The power cable is simply a wire.

Yeah, I just saw that there existed a PS2 model of 700 grams with an integrated power supply Laugh Thank you for reminding me to add this.

Wow I've never seen pins so wrecked to hell lol I also forgot there's a slim with internal PSU. Now you got me daydreaming about a handheld PS2... But not those bulky mods with the DVD drives Wink
