Rev	Log message	Author	Age	Path
160	Logic updates, and bug fix corrections to bring this in line with the current XuLA2-LX25 SoC version. (i.e., the XuLA version was debugged and improved, this update pushes those improvements to the mainline.)	dgisselq	3084d 23h	/zipcpu/trunk/rtl/core/pipemem.v
131	Fixed a variable use before declaration error.	dgisselq	3138d 23h	/zipcpu/trunk/rtl/core/pipemem.v
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	3260d 07h	/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	3321d 08h	/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	3331d 10h	/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	3341d 02h	/zipcpu/trunk/rtl/core/pipemem.v
