SGDMA data transfer question.

Hi, I did a memory transfer test from RAM to SDRAM using SGDMA, the speed test was evaluated using performance counter core, and it shows the transfer rate goes up to 370 MB/s with all con...

This kind of speed is possible with SDRAM if you are using bursts or consecutive accesses, which is usually the case when transferring from a DMA.

If you had random transfers, then asynchronous SRAM could become faster than SDRAM in some cases.
