Abstract:

As the conventional image processing FPGA design has the problem of long design cycle and complex simulation,we propose a hardware design method based on Simulink's powerful image processing capabilities,easy operation,high flexibility and ease of simulation.First we finish the design of functional model,then convert it to a fixed-point model and finally to the HDL model.This method greatly reduces the functional model design cycle due to its pre-image visual simulation,achieving the FPGA implementation of the absolute position sensor within the allowed error range (0.01 millimeter).
