DESCRIPTION:

exchange device intended for inter-bus communication in

interleaved memory systems and high performance multi-

plexed address and data busses.

the CPU A/D bus (CPU address/data bus) and multiple

memory data busses.

control signals suitable for simple transfer between the CPU

bus (X) and either memory bus (Y or Z). The Bus Exchanger

features independent read and write latches for each memory

bus, thus supporting a variety of memory strategies. All three

ports support byte enable to independently enable upper and

lower bytes.
