Dynamically reconfigurable processor (DRP) developed by NEC Electronics is a coarse grain reconfigurable processor that selects a data path from the on-chip repository of sixteen circuit configurations, or contexts, to implement different logic on one single DRP chip. Several stream applications have been implemented on the DRP-1, the first prototype chip, and evaluation results are presented. By pipelining the executions, DRP-1 outperformed Pentium III/4, embedded CPU MIPS64, and Texas Instruments DSP TMS320C67J3 in some stream application examples. We also present programming techniques applicable on dynamically reconfigurable processors and discuss their feasibility in boosting system performance.
