Some time ago I decided to design myself a simple CPU and to go old school I decided to make it a serial bus. I'm still toying with the idea and deciding which technology to use, I had originally thought 74 plus some standard serial RAM.
I still haven't decided but there is a problem with standard Serial RAM in that it is all high bit first and really I need low bit first, especially for the addresses. While it might work with just byte access, more complex multi-byte would be troublesome.
I'm toying with a couple of ideas one is a complete FPGA serial RAM, whilst the other is to use standard parallel RAM via an FPGA interface.
There do not seem to be any serial access cores here, does anyone know of any?
