基于泡沫挤压的图像流水线设计与FPGA验证

在图像处理器中，图像处理过程具有待处理像素量大、处理过程复杂以及数据传输通道多等特点，因而图像处理器存在着处理速度慢的问题。针对该问题，文中提出一种具有泡沫挤压功能的图像流水线FPGA设计方案，并在Xilinx公司的Virtex XC6VLX550T FPGA芯片上对该FPGA实现方案进行了验证和综合，结果表明本设计方案的正确性且同基本流水线相比该流水线设计能够在不大量增加电路资源的情况下提高图像处理器的处理速度。

The FPGA design and implementation of pipeline image processing based on foam extrusion

In the Graphic Processing Unit system, image processing is facing the fact that the image has a large amount of pixel data to be processed, the processing procedure is complicated and the data transmission channels are too many. All of these matters result that Graphic Processing Unit has low processing speed. This paper proposes a FPGA design of the image pipeline in GPU. The design has been implemented by foam extrusion pipeline architecture and validated on Xilinx Virtex XC6VLX550T FPGA. The result shows that comparing with the basic pipeline, the foam extrusion pipeline architecture can improve the processing speed of GPU.
