In order to meet the requirement of fractional signal transform real-time computation, this paper proposes a hardware implementation of reconfigurable fractional signal transform processor based on Altera Stratix Ⅱ FPGA. A common hardware framework is designed and realized based on the angular decomposition algorithm. Taking advantage of the reconfigurable property of FPGA, various fractional signal transform functions can be realized through simple adjustment of parameters. The experiment results indicate this system is very flexible, which gives a good platform for the quickly development of various realtime system based on fractional signal transform.
