NAOMI

NAOMI (New Arcade Operation Machine Idea)

History

The Naomi board 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.
