English abstract:
Virtually all asynchronous design techniques employ pipelining to structure the data path. The classical micropipeline architecture as introduced by Sutherland provides a generic solution to this problem; it is, how- ever, not a delay insensitive approach, since handshak- ing is based on delay elements. So the question arises, whether it is possible to modify this principle and com- bine it with another method such that the resulting ar- chitecture is indeed delay insensitive. In this paper we investigate this question at the exam- ple of CAL, a design method also known as four phase logic. We propose and optimize different pipeline im- plementations and discuss their respective merits and drawbacks along with simulation results and implemen- tation experiences.
