ABSTRACT:
An arrangement to couple at least one I/O device to the main bus between a CPU and a main memory in a digital computer system is shown to include a random access memory made up of a dedicated part of the main memory and control circuitry to allow access between addresses in the random access memory and either the CPU or the at least one I/O device, such circuitry being arranged to give priority of access to the CPU except when data is actually being transferred from the I/O device and the random access memory.
