This paper brought forward some new design schemes based on the principle and signal processing algorithm of velocity detector, and introduced the hardware construction of the velocity detector based on Depolarizer and S3C2410A microprocessor. The high-efficient ARM program of radical 4-FFT was designed according to the architecture characters of ARM core. In the process of code designing, the instruction scheduling and register allocation were controlled subtly, and the fixed-point number's storage format and computing method of float number were provided. Barrel shifter and 5-lever pipeline were fully utilized and the pipeline interlock was avoided.
