201 RTL files for the 8-bit capable ZipCPU. dgisselq 2637d 15h /zipcpu/trunk/rtl/peripherals/wbdmac.v
182 Bug fix for fast memories. This now works for memories with single cycle
latencies.		 dgisselq 2812d 12h /zipcpu/trunk/rtl/peripherals/wbdmac.v
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 2905d 08h /zipcpu/trunk/rtl/peripherals/wbdmac.v
88 Eliminated some warnings. The div fixes were to simplify the logic, even though
the result is less readable ...		 dgisselq 3067d 10h /zipcpu/trunk/rtl/peripherals/wbdmac.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 3080d 17h /zipcpu/trunk/rtl/peripherals/wbdmac.v
48 Files added/updated to get Dhrystone benchmark to work. Several fixes
to the CPU in the process, 'cause it wasn't working. Stall-less ALU
ops now work better, to include grabbing the memory result as it comes out
of the memory unit and placing it straight into either ALU or memory unit
for the next instruction.		 dgisselq 3161d 11h /zipcpu/trunk/rtl/peripherals/wbdmac.v
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 3173d 20h /zipcpu/trunk/rtl/peripherals/wbdmac.v
