You will need to bank switch. Dedicate a section of external address
space for control, and use that to select which bank of 64M you will talk
to at a time. You'll need 1000/64 = 16 banks. A fast CPLD will work fine
for this.

Patience, persistence, truth,

Dear members,
My question is how to use large SDRAM, for example 1GB, in tigersharc based DSP board. It seems that Tigersharc only supports 64MB SDRAM at most.
