The DSP240 controller board supports 64k x 16bit each of on-card Program RAM and Data RAM. This memory is interleaved with the DSP internal memory using the on-chip memory management hardware. The PCB also supports 64k x 16bit EPROM, mapped to the DSP I/O address space. Programs cannot be executed directly from the EPROM memory, but rather the EPROM can be used to store programs, which can be block moved to Program RAM for execution as required. The DSP240 controller board also supports 256 x 16bits of non-volatile serial ROM, which is programmed from the DSP using I/O signals on Port B.
