A port in the world of PSoCs is 8 bits wide and the max frequency DMA runs is 48-80MHz depending on the PSoC. The interesting thing is that for DMA data-transfers no CPU intervention is needed.
But there is more inside a PSoC: there is configurable programmable hardware within from simple gates over FFs, timers counters ADCs DACs amplifiers and and and...
Thank you very much Bob.
One last question:
Is there a more control transfer, like can i use one port for a addressing and the other as a data port?
What kind of reads, in mega Hz, can i get from change the address, read data, repeat?
This is for The best board or what board you are most familiar with, PSoC 1, 2, 3, 4, 5.
It Can be a rough estimate.
You can use the External Memory Interface (EMIF) to do that. I thnink the max speed of around 33m.
