Hi,

I have one basic doubt on how MEMORY WR/RD# cycles are emulated.. (i.e
memory read & write cycles emulated in software)..

How is the Assertion/Deassertion of WR/RD pins taken care (emulated) in
software whenever a memory address is being deferenced.

Thanks

Simple, you don't have to worry about it. That's too low level for a CPU
emulator.

As noted, this is very low level. Indeed, it depends on the type of
memory (DDR SDRAM, SDRAM, Sync Flash/ROM/SRAM, Async devices) and even
then the requirements can vary greatly (that's one reason why memory
controllers have so many settable parameters).

Why do you ask?

Cheers
