Central Processing Unit:
(R3051) MIPS R3000A-Compatible 32-bit RISC Chip running at 33.8688 MHz.
The chip is manufactured by LSI Logic Corp, with technology licensed from SGI.
Features:
Operating Performance of 30 MIPS (Million Instructions Per Seccond)
Bus bandwidth 132 MB/s.
4 KB Instruction Cache.
1 KB non-associative SRAM Data Cache.
2 MB of main RAM.
Geometry Transformation Engine:
Resides inside the main CPU chip, giving it additional vector math instructions used for 3D graphics.
Features:
Operating Performance of 66 MIPS.
360,000 flat-shaded Polygons per second.
180,000 Texture Mapped and Light-Sourced Polygons per second.
Theoretical Polygon count in optimal conditions given by Sony.
1 Million flat-shaded Polygons per second.
500,000 Texture Mapped and Light-Sourced Polygons per second.
Data Decompression Engine:
Also residing within the main CPU, it is responsible for decompressing images and video.
Documented Device Mode is to read three RLE-encoded 16×16 macroblocks, run IDCT and assemble a single 16×16 RGB Macroblock.
Output data may be transferred directly to the GPU via DMA.
It is possible to overwrite IDCT matrix and some additional parameters, however the MDEC internal instruction set was never documented.
Features:
Compatible with MJPEG and H.261 files.
Operating Performance of 80 MIPS.
Directly Connected to the CPU Bus.
Graphics Processing Unit:
Handles 2D graphics processing separate from the main 3D engine on the CPU.
Features:
Maximum of 16.7 Million Colors (24-bit Color Depth).
Resolutions from 256 × 224 to 640 × 480.
Adjustable Frame Buffer.
Unlimited Color lookup tables.
Emulation of simultaneous backgrounds (for parallax scrolling).
Flat or Gouraud Shading and Texture Mapping.
1 MB of VRAM.
Sound Processing Unit:
Supports ADPCM sources with up to 24 channels.
Sampling rate of up to 44.1 kHz.
512 KB of Memory.
