An instruction set architecture independent design method for embedded OFDM-based software defined transmitter

Abstract

An instruction set architecture independent design method targeted on embedded software defined radio is proposed. Without the aid of specified instructions, this work focuses on cycle-efficient implementation of bit-oriented operations on word-based processors. High portability between platforms is achieved and demonstrated with an IEEE 802.11a (WiFi) transmitter implemented in C language on both Sandbridge Technologies© Inc. SB3011 baseband processor evaluation board and Texas Instruments© Inc. TMS320 C64x digital signal processor. More than 99% instruction cycle reductions are observed on both platforms.
