Control network generator for latency insensitive designs

—Creating latency insensitive or asynchronous designs from clocked designs has potential benefits of increased modularity and robustness to variations. Several transformations have been suggested in the literature and each of these require a handshake control network (examples include synchronous elasticization and desynchronization). Numerous implementations of the control network are possible. This paper reports on an algorithm that has been proven to generate an optimal control network consisting of the minimum number of 2-input join and 2-output fork control components. This can substantially reduce the area and power consumption of a system. The algorithm has been implemented in a CAD tool, called CNG. It has been applied to the MiniMIPS processor showing a 14% reduction in the number of control steering units over a hand optimized design in a contemporary work.
