A Symbiotic Partnership Between FPGA And 6502
See the original posting on Hackaday
[Kenneth Wilke] is undertaking a noble quest – to build a homebrew microcomputer, based around the venerable 6502. As a prelude to this, he set out to interface the hallowed CPU to an FPGA, and shared the process involved.
[Kenneth] is using an Arty A7 FPGA development board which is a great fit for purpose, having plenty of I/O pins and being relatively easy to work with for the home tinkerer. This is an important consideration, as many industrial strength FPGAs require software licences to use which can easily stretch into the tens of thousands of dollars.
The 6502 is …read more
