79	Adjusted the opcodes for NOOP, BREAK, and LOCK.	dgisselq	3091d 01h	/zipcpu/trunk/doc/
78	Found/corrected annoying bug in floating point documentation of the opcode table.	dgisselq	3091d 01h	/zipcpu/trunk/doc/
73	Documentations updates.	dgisselq	3092d 00h	/zipcpu/trunk/doc/
72	Some updated graphics, now containing images of the CPU that include the divide and (currently non-existant) floating point unit.	dgisselq	3092d 01h	/zipcpu/trunk/doc/
69	This implements the "new Instruction Set" architecture for the Zip CPU. It's a massive change set, that touches just about everything but probably not enough of everything. Please see the spec.pdf for a description of this new architecture.	dgisselq	3098d 05h	/zipcpu/trunk/doc/
68	Updated specification, includes well illustrated pipeline discussion.	dgisselq	3133d 05h	/zipcpu/trunk/doc/
67	Includes timing diagrams in support of a very descriptive specification section.	dgisselq	3133d 05h	/zipcpu/trunk/doc/
49	Final set of changes finishing the Dhrystone package. Dhrystone, as implemented by hand in assembly, now works.	dgisselq	3178d 23h	/zipcpu/trunk/doc/
47	Added some new graphics, includes the file for the Zip Bones system.	dgisselq	3178d 23h	/zipcpu/trunk/doc/
39	Here's the documentation update to support the pipelined read/writes of the bus from the CPU, as well as the test file that proved they worked.	dgisselq	3182d 02h	/zipcpu/trunk/doc/
37	Fixed some minor spelling errors.	dgisselq	3190d 19h	/zipcpu/trunk/doc/
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.	dgisselq	3191d 08h	/zipcpu/trunk/doc/
35	I updated the system diagram to reflect the new version that has a direct memory access controller, rather than the (useless) manual cache.	dgisselq	3207d 22h	/zipcpu/trunk/doc/
33	Finally finished a first draft of the full specification!	dgisselq	3220d 01h	/zipcpu/trunk/doc/
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.	dgisselq	3220d 09h	/zipcpu/trunk/doc/
24	Lots more changes to the spec. It's still not done, but it is more complete than before.	dgisselq	3223d 10h	/zipcpu/trunk/doc/
23	Oops -- left some portions of the RTC Clock spec in with the ZIP CPU spec. These were quickly removed.	dgisselq	3225d 06h	/zipcpu/trunk/doc/
22		dgisselq	3225d 06h	/zipcpu/trunk/doc/
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.	dgisselq	3225d 06h	/zipcpu/trunk/doc/
10	Here's the watchdog timer code, as well as some pictures of the register set.	dgisselq	3245d 23h	/zipcpu/trunk/doc/
