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	3268d 11h	/zipcpu/trunk/rtl/core/pipemem.v
63	Simplified bus interactions, and added support for detecting illegal instructions (i.e. bus errors) in the pipefetch routine.	dgisselq	3329d 11h	/zipcpu/trunk/rtl/core/pipemem.v
56	Here's a bit of work in progress for getting the Zip CPU working on a XuLA2 board. Many changes include: the existence of a cpudefs.v file to control what "options" are included in the ZipCPU build. This allows build control to be separated from the project directory (one build for a XuLA2 board, another for a Basys-3 development board). Other changes have made things perhaps harder to read, but they get rid of warnings from XST. A big change was the addition of the (* ram_style="distributed" *) comment for the register set. This was necessary to keep XST from inferring a block RAM and breaking the logic that was supposed to take place between a register read and when it was used.	dgisselq	3339d 14h	/zipcpu/trunk/rtl/core/pipemem.v
49	Final set of changes finishing the Dhrystone package. Dhrystone, as implemented by hand in assembly, now works.	dgisselq	3349d 05h	/zipcpu/trunk/rtl/core/pipemem.v
