Performance optimization of synchronous control units for datapaths with variable delay arithmetic units

摘要

Nowadays, variable delay arithmetic units have been used for implementing a datapath of a target system in pursuit of performance improvement. However, adoption of variable delay arithmetic units requires modification of a typical synchronous control unit design methodology. A telescopic arithmetic unit based methodology is one of representative methodologies to design synchronous control units for variable delay datapaths. In this paper, we propose two optimization methods for it. Proposed optimization techniques will be analyzed in order to show their performance improvement effects explicitly.
