| 摘 要： | 针对传统图像处理FPGA设计的设计周期长,仿真验证复杂等问题,提出了采用Simulink的硬件设计方法。该方法以具有强大图像处理能力、操作简便、灵活性高,并以便于仿真的Simulink为基础,进行了功能模型的设计,再将其转换为定点模型及HDL模型。该方法由于前期图像可视化的仿真,大幅缩减了功能模型设计周期,并在允许误差范围内(0.01 mm)完成了对绝对位置传感器的FPGA实现。

| 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). |
