SDRAM is still in use in the memory, although the subsequent DDR replaced, it is important to master it. Before debugging, it really cost a great effort, its complexity is undoubtedly, the general people want to understand him, it will take about 1 months, at least I think so. What is the role of SDRAM, anyway? The answer must be storage, if you do not use it in the project, it is difficult to appreciate the role of it, recently in the SDRAM VGA display, in fact, adjusted well, it is not so magical. First to the high-frequency 100M to the SDRAM write data, and then read the data, because the VGA clock frequency of 25M, it is certainly not directly to the VGA, the SDRAM read data needs to be cached in the Dcfifo, through the DCFIFO output 25M frequency data, to the VGA, This allows the data in the SDRAM to be transitioned to VGA for real-time display.
