PlayStation technical specifications
PlayStation technical specifications describe the various components of the original PlayStation video game console.
Central processing unit (CPU) LSI CoreWare CW33300-based core  Geometry Transfer Engine (GTE) Coprocessor that resides inside the main
CPU processor, giving it additional vector math instructions used for 3D graphics, lighting, geometry, polygon and coordinate transformations – GTE performs high speed matrix multiplications. Operating performance: 66
MIPS  Polygons per second (rendered in hardware):
Motion Decoder (MDEC) Also residing within the main CPU, enables full screen, high quality FMV playback and is responsible for
decompressing images and video into VRAM.  Operating performance: 80
MIPS  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
GPU via DMA. It is possible to overwrite
IDCT matrix and some additional parameters, however MDEC internal instruction set was never documented. Features:
MJPEG and H.261 files Directly connected to CPU bus System Control Coprocessor (Cop0) This unit is part of the CPU. Has 16 32-bit control registers.
Modified from the original R3000A cop0 architecture, with the addition of a few registers and functions.
Controls memory management through virtual memory technique, system interrupts, exception handling, and breakpoints. Memory 2
MB main EDO DRAM  Additional RAM is integrated with the GPU (including a 1 MB
framebuffer) and SPU (512 KB), see below for details. Cache RAM for CPU core and CD-ROM. See the relevant sections for details.
Flash RAM support through the use of memory cards, see below.
BIOS stored on 512 KB ROM Graphics processing unit (GPU) 32-bit Sony GPU Handles display of
graphics, control of framebuffer, and drawing of polygons and textures Handles
2D graphics processing, in a similar manner to the 3D engine RAM:
framebuffer (1024×512) Emulation of simultaneous backgrounds (to simulate
parallax scrolling) Mask bit
Alpha blending (4 per-texel alpha blending modes)
Render to texture
Flat or Gouraud shading and texture mapping  No line restriction
Colored light sourcing
Texture mapping color mode:
 Mode 4: 4-bit CLUT (16 colors)
Mode 8: 8-bit CLUT (256 colors)
Mode 15: 15-bit direct (32,768 colors)
Mode 24: 24-bit (16,777,216 colors)
Special sprite effects:
Vertical and horizontal line scroll Sound processing unit (SPU) 16-bit Sony SPU  I/O system and connectivity CD-ROM drive 660
MB maximum storage capacity, double speed CD-ROM drive 2×, with a maximum
data throughput of 300 KB/s (double speed), 150 KB/s (normal)  128 KB
XA Mode 2 compliant Audio CD play
 CD-DA (CD-Digital Audio) Two control pads via connectors  Expandable with multitap connector  Backup flash RAM support Two removable cards
 Each card has 128 KB flash memory
OS support for File Save, Retrieve and Remove  Video and audio connectivity Serial and parallel ports Power input 100 VAC (NTSC-J)/120 VAC (NTSC-U/C)/220–240 VAC (PAL)
