CPLD - what memory
Hello everybody,
I'm trying to build simple fuzzy controller based on Xilinx CoolRunner series CPLD. The fuzzy is somehow ok, but since I'm newbie in the field of CPLD design, I would like to ask someone more experienced: I need to use small (1-2-3 k maximum) look-up table with this CPLD (CoolRunner II or XPLA3 - not important). Can anyone suggest what memory chip to use since the CPLD have no user customizable ROM inside itself. And how to interface this memory?
/Reasons to use CPLD and not FPGA are package, price and power consumption. Plus I would like to know how to use external memories with programmable logic./
I will appreciate any help - link or simple example or even an idea on how to start.
Thank you very much.
