Abstract
This paper presents SWIFT, a computationally intensive DSP Architecture for communication applications. We introduce the VLIW feature and SIMD capability of SWIFT, and the vector register file, store buffer, multi-banked memories as well. Then, the structure of nine stages pipeline with powerful bypass logics is disclosed. Finally, the hardware implementation of SWIFT is shown. In SWIFT, computation, data access and control operation can be handled orthogonally. With the efficient SIMD feature, multi-accessible local data memories, and the fine-tuned VLIW instructions, it is possible to achieve high utilization of the DSP datapath in SWIFT.
