It is well known that FIR algorithm based on normal DSP has low computing speed and extensive capabilities. In order to overcome these,present a new FIR filter algorithm based on CUDA platform. Since in CUDA program can directly manipulate data without graphics API of the system,enables developers on the basis of the powerful GPU computing power to set up a efficient dense data computing solutions. The algorithm adopts CUDA for FIR filter calculation of input and output relationship,using the parallel compu...
