This dissertation demonstrates that substantial speedup over conventional single-chip microarchitectures can be achieved by a single-chip microarchitecture exploiting deep pipelining, out-of-order execution, multiple operations per instruction, and multiple function units. We have measured the speedup one can potentially achieve with a microarchitecture exploiting local parallelism. We have developed a checkpoint repair mechanism to demonstrate that a microarchitecture exploiting local parallelism need not suffer from inconsistent states when exceptions occur. HPSm, a single-chip microarchitecture, has been designed as the first prototype of our execution model exploiting local parallelism. Experiments have been conducted to demonstrate the effectiveness of HPSm as compared to a popular single-chip microarchitecture, the Berkeley RISC/SPUR. Evaluations have been done with both control intensive and floating point intensive benchmarks. For both types of benchmarks, the HPSm microarchitecture achieves significant speedup over the Berkeley RISC/SPUR implemented with the same fabrication technology.
