I have a new cache. Researched it as best as possible and it appears to be new. Anyone interested? Address matching in less than 10% overhead of the cache RAM size in implementation for any size. Not really interested in developing it myself. Useful for gigahertz CPUs, missiles, supercomputers, mobile phones, graphics cards, encryption, compression, and so on. One or two months to modify vhdl of a 6502 or something like that to see it working, and then tape it out as fast as your legs can carry. Its 2 or 3 pages to describe it in full in English. One hour to do a presentation. I'm interested in serious proposal.

Sure. Tell us all about it.

I'm not sure if I would want to add a cache to a 6502 but you could design an upgrade that could replaced the 6502 with a 65816/65C816. The advantage of the 65816/65C816 is that it runs at 4 - 8 mhz and the original CPU was 1 - 2 mhz giving it a 2x - 8x the performance. The other big bonus is that you should be able to use SRAM cache that is the same size as the address space of the 6502. I'm sure it would make a Commodore VIC/C64/C128 or Apple II owner very happy.
I'm sorry I just miss Commodore and the computers they use to make. Oh well back to work.
