Register Synthesis for Speculative Computation

The late release policy of conventional renaming keeps many registers in the register file assigned in spite of containing values that will never be read in the future. In this work, we study the potential of a novel scheme that speculatively releases a ...

Multimedia and network processing applications make extensive use of subword data. Since registers are capable of holding a full data word, when a subword variable is assigned a register only part of the register is used. We propose an instruction set ...

This paper explores Speculative Precomputation, a technique that uses idle thread context in a multithreaded architecture to improve performance of single-threaded applications. It attacks program stalls from data cache misses by pre-computing future ...
