#93336 - jump cache Responding to: ???'s previous message |

I'm not aware of ANY other 8-bit CPU which (need to) incorporate a cache. The (already mentioned) uPSD34xx (and uPSD33xx) do (although in a simpler implementation), due to the same problem - the code FLASH is too slow to allow a byte fetch each 10 ns (for the fastest silabs) nor 25 ns (for the uPSDs).
