硬件规格:
The NAOMI (New Arcade Operation Machine Idea) is also Japanese for beauty above all else.
CPU : 2 x Hitachi SH-4 32-bit RISC CPU (200 MHz 360 MIPS / 1.4 GFLOPS)
Graphic Engine : 2 x PowerVR 2 (PVR2DC-CLX2) GPU's - (under the fans)
Geometry Processor : Custom Videologic T+L chip "Elan" (100mhz) - (Under Heatsink)
Sound Engine : ARM7 Yamaha AICA 45 MHZ (with internal 32-bit RISC CPU, 64 channel ADPCM)
Main Memory : 32 MByte 100Mhz SDRAM
Graphic Memory : 32 MByte
Model Data Memory : 32MByte
Sound Memory : 8 MByte
Media : ROM Board / GD-Rom
Simultaneous Number of Colors : Approx. 16,770,000 (24bits)
Polygons : 10 Million polys/sec with 6 light sources
Rendering Speed : 2000 Mpixels/sec (unrealistic max, assumes overdraw of 10x which nothing uses)
Additional Features : Bump Mapping, Multiple Fog Modes, 8-bit Alpha Blending (256 levels of transparency), Mip Mapping (polygon-texture auto switch), Tri-Linear Filtering, Super Sampling for Full Scene Anti-Aliasing, Environment Mapping, and Specular Effect.
Compatibility : Fully backwards compatible with all Naomi and GD-Rom games.
Notes : Notice that Naomi 2 has four time the amount of main memory and graphics memory that Dreamcast has, and twice that of the naomi so ports from Naomi to Dreamcast may involve more conversion time and a great loss of texture detail. Also note that the Naomi2 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.
