Abstract
A two-level controller for a system interface between an auxiliary processor and main memory modules of a multiprocessing system which respective processor and system have different clock rates, memory access times and memory addressing capabilities. The two-level controller is formed of a hierarchy of two control stores wherein the receipt of a command code by the first control store from the processor causes it to address the second control store. Each control store is provided with program counter means to receive its respective address and to increment that address until it receives a new address so as to asynchronously control simultaneous operation of a memory interface to said memory modules and a cache mechanism coupled to the processor.
