Supporting multithreading in configurable soft processor cores

In this paper, we describe the organization and microarchitecture of MT-MB, a configurable implementation of the Xilinx MicroBlaze soft processor that supports multithreading. Using a suite of synthetic benchmarks, we evaluate five variations of MT-MB and show that multithreading is very effective in hiding the variable latencies associated with custom instructions and custom computational units. Our experimental results show that interleaved and hybrid mul
