基于 FPGA 与 DDR3 缓存的 PAL 制式图像源产生模块设计与实现.

To realize rapid test of the key performance of the products in the environment test, and simulate a 4-channel PAL camera output in parallel, an image source generating module based on FPGA and DDR3 was designed. The YCrCb format image source was encoded according to ITU-RBT. 656 standard, and the ADV7393 chip was used to realize the PAL format conversion, the DDR3-SDRAM stored and outputted data by a method of partition storage and pipelined rotation. It has been proved that the module can effectively output 4 image sources in parallel, and by circuit expansion, the test efficiency can be strongly improved. [ABSTRACT FROM AUTHOR]
