Rev	Log message	Author	Age	Path
73	Documentations updates.	dgisselq	3608d 21h	/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	3608d 21h	/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	3615d 02h	/zipcpu/trunk/doc/
68	Updated specification, includes well illustrated pipeline discussion.	dgisselq	3650d 02h	/zipcpu/trunk/doc/
67	Includes timing diagrams in support of a very descriptive specification section.	dgisselq	3650d 02h	/zipcpu/trunk/doc/
49	Final set of changes finishing the Dhrystone package. Dhrystone, as implemented by hand in assembly, now works.	dgisselq	3695d 20h	/zipcpu/trunk/doc/
47	Added some new graphics, includes the file for the Zip Bones system.	dgisselq	3695d 20h	/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	3698d 23h	/zipcpu/trunk/doc/
37	Fixed some minor spelling errors.	dgisselq	3707d 16h	/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	3708d 05h	/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	3724d 19h	/zipcpu/trunk/doc/
33	Finally finished a first draft of the full specification!	dgisselq	3736d 22h	/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	3737d 06h	/zipcpu/trunk/doc/
24	Lots more changes to the spec. It's still not done, but it is more complete than before.	dgisselq	3740d 06h	/zipcpu/trunk/doc/
23	Oops -- left some portions of the RTC Clock spec in with the ZIP CPU spec. These were quickly removed.	dgisselq	3742d 02h	/zipcpu/trunk/doc/
22		dgisselq	3742d 02h	/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	3742d 02h	/zipcpu/trunk/doc/
10	Here's the watchdog timer code, as well as some pictures of the register set.	dgisselq	3762d 19h	/zipcpu/trunk/doc/
8	Fixed the rotate left instruction to work in the zasm parser, and to be properly referenced in the simulator. The instruction set documentation was also adjusted to reflect what the CPU actually does.	dgisselq	3763d 02h	/zipcpu/trunk/doc/
7	Here's the iset.html file that was at one time in the gfx directory, but which could not be moved due to a bad gateway error ... (Grrr).	dgisselq	3763d 03h	/zipcpu/trunk/doc/
