PIO performance

Hi, I use IORD and IOWR to control the PIO and it seems the speed will be no more than 15MHz. Is there any way to accelerate?

FYI it's not that the PIO is slow, the processor accessing the PIO can't access it every clock cycle. If you wired a DMA up to the PIO you could potentially change the output every clock cycle.
