FPGA FIFO 读取模式分两种:
Normal Mode: In normal mode, the “rdreq” signal serves as the read request or read enable. When this signal goes high, the data output provides the first data from the FIFO.Essentially, in normal mode, data is availa…
1.SDRAM和SRAM的区别
SRAM不需要刷新电路即能保存它内部存储的数据。而SDRAM(Dynamic Random Access Memory)每隔一段时间,要刷新充电一次,否则内部的数据即会消失,因此SRAM具有较高的性能,但是SRAM也有它…
