How to realize the port transform from ARM to ISA bus

[malcolm_119]

I need to expand a ISA bus from EPM9315 (ARM CPU) , But I learned CPLD for a shot time , and I have no idea of it, Please give me a hand or a demo code of verilog , Thanks a lot ~~

How much support of isa do you need:

-8/16 bit transfers?
-IO addressing ?
-Memory addressing?
-DMA?
-correct ISA access timing?

If you like all, it is a more complex task.

Have not looked at the CPU you mentioning, but likely only supporting for only 8bit mem addressing, likely you don't need any PLD, direct coonnection likely will do the trick.
