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

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.
