Automatic parallelization by compiler is one way to better utilize multiple cores. Unfortunately, the best performing compiler techniques, such as those in the DSWP (Decoupled Software Pipelining) family of transformations, employ speculation and rely on dynamic information obtained by profiling, a technique unpopular with developers. Runtime techniques, such as Just-In-Time compilers, can address the popularity-of-profiling problem, but they are limited in the amount of dynamic information they can collect without negatively impacting overall program performance. Noting that existing processors already include structures that gather the type of information speculative thread extraction techniques need, I explore the possibility of performing thread extraction transformations in hardware and propose HW-DSWP (Hardware - DSWP) parallelization technique. The framework identifies hot loops based on the trace of backward branches, calculates dependency depth of instructions and segregates the instruction stream into critical and non-critical set which would then be executed on the main thread and additional thread respectively.
