[/] [zipcpu/] [trunk/] [rtl/] [core/] [pipemem.v] - Rev 63

Rev	Log message	Author	Age	Path
63	Simplified bus interactions, and added support for detecting illegal instructions (i.e. bus errors) in the pipefetch routine.	dgisselq	3302d 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	3312d 11h	/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	3322d 02h	/zipcpu/trunk/rtl/core/pipemem.v
