Designing asynchronous circuits is becoming easier as a number of design styles are making the transition from research projects to real, usable tools. However, designing asynchronous "systems" is still a difficult problem. We define asynchronous systems to be medium to large digital systems whose descriptions include both datapath and control, that may involve non-trivial interface requirements, and whose control is too large to be synthesized in one large controller. ACK is a framework for
more » ... a framework for designing highperformance asynchronous systems of this type. In ACK we advocate an approach that begins with procedural level descriptions of control and datapath and results in a hybrid system that mixes a variety of hardware implementation styles including burst-mode AFSMs, macromodule circuits, and programmable control. We present our views on what makes asynchronous high level system design different from lower level circuit design, motivate our ACK approach, and demonstrate using an example system design.
