Abstract

The PreCoRe approach allows the automatic generation of application-specific microarchitectures from C, thus supporting complex speculative execution on reconfigurable computers. In this work, we present the PreCoRe capability of using data-value speculation to reduce the latency of memory reads, as well as the lightweight extension of static datapath controllers to the dynamic replay of misspeculated operations. The experimental evaluation considers the performance / area impact of the approach and also discusses the individual effects of combining different speculation mechanisms.
