摘　　要：针对嵌入式软件无法满足数字图像实时处理速度问题,提出用硬件加速器的思想,通过FPGA实现Sobel边缘检测算法。通过乒乓操作、并行处理数据和流水线设计,大大提高算法的处理速度。采用模块的硬件设计,保证了系统的可移植性和系统的扩展性。最后使用Verilog HDL编程实现算法处理,并用Modelsim和MATLAB进行了仿真和验证。Aiming at the problem that embedded software can ′ t meet the digital image real- time processing speed, this thesis puts forward the idea of using hardware accelerators, that is, using FPGA hardware to implement Sobel edge detection algorithm. Through Ping- pong operation, parallel processing data and pipeline design, the processing speed of the algorithm is greatly improved. The hardware design of module ensures the portability and scalability of the system. Finally, this thesis applies Verilog HDL program-ming to realize the algorithm processing and uses Modelsim and MATLAB to make simulation and verification.
