The foundation board provides the basic EmPack control and
communications infrastructure. The two Hitachi SH7032 processors
communicate with each other through 8KB of dual-ported SRAM
and each has its own local SRAM. The back end processor has 1MB
of flash memory, up to 8MB of global DRAM and controls the SCSI,
SCSA, TDM and mezzanine buses.
The front-end processor controls the T1/E1 and audio interfaces.
