Hello,
Are there any good examples available on how to make wider memory when all you have connected to you FPGA hardware is byte-wide memory? I'm talking about static RAM, not block RAM or other memory bits inside a FPGA chip. I have searched a bit, but perhaps I'm using the wrong search words. I'm quite new to using FPGAs.
Background:
I am trying to adapt (port? not sure about terminology here) Project Oberon (
http://www.projectoberon.com/) so it will run on Multicomp board, like this one
https://www.retrobrewcomputers.org/doku ... ii-c:start(Multicomp is Grant Searle's creation:
http://searle.wales/).
Anyway, the Multicomp board has two AS6C4008 RAM chips connected to it, so that the data bus is 8-bit. And the RISC5 cpu in the computer that runs Project Oberon wants a 32-bit wide memory..
So I need a way to do that.
Not sure it will work out at all, the result might be too slow (reading 4 bytes in sequence rather than one 32-bit word) but it is fun to try.
Any help or pointers to places I can learn more is appreciated.
