Abstract
A system for interfacing asynchronous machines. The system includes a single-port RAM (Random Access Memory) synchronized with the master clock of only one of the asynchronous machines, and a FIFO (first in/first out) memory. The devices to implement this system consist of a single-port RAM, an FIFO memory, two counters, one of which is a write counter and the other is a read counter, a multiplexer which selects one of the two counters, and a RAM access control logic which generates the RAM control signals and the counter enabling signals and the above mentioned multiplexer select signal.
