Explicitly multithreaded processors and reconfigurable hardware have individually proven to be useful in the design of wireless communication systems. However, new techniques are needed to satisfy the processing requirements of emerging wireless communication standards, which have high throughput requirements for a wide variety of algorithms. This paper presents an efficient technique for adding reconfigurable functional units, called Polymorphic Hardware Accelerators (PHAs), to multicore, multithreaded Digital Signal Processors (DSPs). This paper discusses architectural support to facilitate management and sharing of PHAs on a multithreaded system. The proposed technique shows an average speedup of 6.8 on important wireless communication algorithms in the EEMBC Telecom Benchmark Suite and Department of Defense's Joint Tactical Radio System Software Communication Architecture (JTRS SCA) Hardware Supplement.
