Abstract
This paper approaches the problem of building an asynchronous control for a stage of the Sproull's Counterflow Pipeline Processor (CFPP) that does not need arbiters. It is shown that there is no arbitration situations in a synchronous pipeline control circuit with two-track synchronization. An asynchronous control circuit can be built by a synchronous prototype with help of GALA-methodology using the procedure of synchro-stratum designing we suggested earlier.
