I read that the BX has 128 Kib of block RAM. So, 16 KiB.
I designed a 6502 computer last year and I was thinking of changing it to utilize the BX for video and memory decoding. Video would be driven from external RAM.
However, I was also thinking that the 16 KiB could be used as ROM for the 6502. I’m really new to FPGA design. Is this even possible? Could I upload some binary 6502 code file into the FPGA and have it reside in the BRAM?
