Abstract:

Both in the radar system and the communication system,when simulating its various signal processing methods,Data participates in computing in the form of floating-point,while the algorithms are implemented in hardware (FPGA),The data participate in the operation in the form of fixed-length binary.This article firstly describes how to use Fixed-Point toolbox to achieve the data conversion from the floating-point to the fixed-point.Finally,an example is designed to describe the application of fixed-point simulation to the verification in FPGA.Experiments show that,The fixed-point simulation is the basis of the implementation of FPGA,and also verify the correctness of the result of FPGA.

Key words: signal processing;fixed-point toolbox;FPGA;verification
