As a kind of wireless communication system, OFDM systems are widely used in the current and next generation wireless communications. According to the characteristics of OFDM systems, this paper proposed a new heterogeneous multi-core DSP architecture for OFDM system - HeteroM-DSP. Hetero M-DSP based on VLIW DSP core, which has good Data-Level Parallelism and Instruction-Level Parallelism. Each independent DSP core through sharing memory, task scheduling bus and bus controller based open-ring interconnection, improve the communications parallelism between DSP cores. Meanwhile, in order to implement different OFDM systems flexibly, each DSP core has different computational capabilities. It is also improved processor performance/ power rate. Experimental results for the IEEE 802.11a receiver show that Hetero M-DSP can efficiently use for OFDM systems.
