A VLIW DSP for communication applications

In this paper, we propose a VLIW DSP architecture SWIFT for communication applications. The SWIFT core includes four parallel SIMD datapath. Each VLIW instruction includes up to four sub-instructions. Therefore, computation, data access and control operation can be handled orthogonally to improve computation performance. Then the pipeline structure, register file, and memory structure of SWIFT DSP are disclosed. Also, the implementation of SWIFT is shown in the paper. With the features of VLIW instruction architecture, SIMD datapath and multi-banked memories, the SWIFT can achieve high data throughput when performing varies algorithms of communication systems. The SWIFT DSP offers a feasible way to implement a high performance SDR platform.
