#98976 - E5 Responding to: ???'s previous message |
The Triscend E5 (now Zylogic ZE5) had a DMA controller - you could take a look at that for some ideas?
Basically, you just need a set of registers to control the DMA (source address, destination address, length, etc) and an interrupt (or status register) to tell the processor when it's done. As you're working with a "soft" 8051, you presumably have the choice of whether you map the registers into SFR or XDATA space? See your documentation for details... |
