Research has shown that precomputation microthreads can be useful for improving branch prediction and prefetching. However, it is not obvious how to provide the necessary microarchitectural support, and few details have been given in the literature. By judiciously constraining microthreads, we can easily adapt a superscalar machine to support many simultaneous microthreads. The nature of precomputation microthreads also requires efficient usage of resources. Our proposed implementation
