In this paper, we introduce a hardware acceleration technique for the parallel Finite Difference Time Domain (FDTD) method using the SSE (Streaming SIMD (Single Instruction Multiple Data) Extensions) instruction set. The implementation of SSE instruction set to parallel FDTD method has been achieved the significant improvement on the simulation performance. The benchmarks of the SSE acceleration on both the multi-CPU workstation and computer cluster have demonstrated the advantages of VALU (Vector Arithmetic Logic Unit) acceleration over GPU acceleration. Several engineering applications are employed to demonstrate the performance of parallel FDTD method enhanced by SSE instruction set.
