Dynamically Reconfigurable Instruction Set for Software Radio Encoding/Coding

Software Radio, considered as a new technology for wireless communication area, implements various communication standards on a uniform hardware by moving calculational tasks onto Digital Signal Processor (DSP). As a result, demanding for DSP´s calculational capabilities is growing and general purpose DSPs is incompetent for the works. In addition, general purpose DSPs´ power and cost are not satisfying while using in software radio. Based on researching various kinds of arithmetic together, this article presents a novel dynamically reconfigurable instruction set for software radio encoding and coding. The application-specific system supplies high computational performance. The instruction set economizes area and reduces power consumption by dynamic reconfiguration. The system is aimed at satisfying requirements of software radio.
