Low power RS codec using cell-based reconfigurable processor

Abstract

This paper describes a low power reconfigurable processor for Reed Solomon (RS) Codec. The Reed Solomon Processor targets handheld devices that use emerging communication standards such as WiMAX and DVB-H. Different design approaches and optimization techniques have been applied in order to enhance the processor throughput and reduce its energy consumption. The throughput achieved is up to 200 Mbps and 92 Mbps for the encoder and decoder respectively. Associated dynamic energy consumption is in the range of 0.34 to 1.17μϋ demonstrating a design suitable for present and future handheld devices.
