SEGA NAOMI GD-ROM HARDWARE
[ BACK TO MAIN PAGE ] - [ TAITO HARDWARE PAGE ]
 
HARDWARE DESCRIPTION
The NAOMI (New Arcade Operation Machine Idea) is also Japanese for beauty above all else.
Main Ram : 32 megs
CPU : SH-4 64-bit RISC CPU (200 MHz 360 MIPS / 1.4 GFLOPS)
Graphic Engine : PowerVR (PVR2DC)
Sound Engine : ARM7 Yamaha AICA 45 MHZ (with internal 32-bit RISC CPU, 64 channel ADPCM)
Main Memory : 32 MByte
Graphic Memory : 16 MByte
Sound Memory : 8 MByte
Media : ROM Board (maximum size of 168 MBytes) / GD-Rom
Simultaneous Number of Colors : Approx. 16,770,000 (24bits)
Polygons : 2.5 Million polys/sec
Rendering Speed : 500 M pixel/sec
Additional Features : Bump Mapping, Fog, Alpha-Bending (transparency), Mip Mapping (polygon-texture auto switch), Tri-Linear Filtering, Anti-Aliasing, Environment Mapping, and Specular Effect.

Notes : Notice that Naomi has twice the amount of main memory and graphics memory that Dreamcast has, so ports from Naomi to Dreamcast may involve more conversion time. Also note that the Naomi board has four times the sound memory of the Dreamcast, and the reason for this is because the Naomi board is'nt meant to spool redbook audio from the GD-ROM drive.

The Naomi architecture is very flexible in that a cabinet can have anywhere from 1 to 16 boards. A multi board system would operate in parallel increasing the power of the system tremendously! Theoritically a 16 board Naomi system could do (16 x 3.5 mpps) = 56 million polygons per second maximum! Realistically it would most likely be around 20 to 30 mpps. Then of course there is also the issue of the CPU being capable of driving all of this hardware.
