36 *Lots* of changes to increase processing speed and remove pipeline stalls.

Removed the useless flash cache, replacing it with a proper DMA controller.

"make test" in the main directory now runs a test program in Verilator and
reports on the results.

33 Finally finished a first draft of the full specification! dgisselq 2458d 12h /zipcpu/trunk/doc/src/
32 Updated the document to match the most recent changes to the CPU. Specifically,
these include the re-instatement of the full SUB command with immediate offset,
and ... others I cannot remember.

The new document also describes what conditions create pipeline stalls,
together with how many cycles each stall condition will create.

24 Lots more changes to the spec. It's still not done, but it is more complete
than before.
dgisselq 2461d 20h /zipcpu/trunk/doc/src/
23 Oops -- left some portions of the RTC Clock spec in with the ZIP CPU spec.
These were quickly removed.

22 dgisselq 2463d 16h /zipcpu/trunk/doc/src/
21 This update adds an incomplete version of the specification for the chip.
I ned to come back to this and do a lot more writing, but it is a start.
