6.1.5. Voice Buffer SRAM
The SRAM used is 8Mbit x 1. This system uses SRAM as the relay buffer for voice data between the DSPs and HDD. The voice
buffer has memory area for four seconds per channel on both A and B sides, giving a total of 24 channels x 4sec (A) x 4sec
(B). The ASIC (iVDC) controls the voice buffer through a bus independent from the system bus.
