182 Bug fix for fast memories. This now works for memories with single cycle
latencies.
dgisselq 2377d 21h /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 2470d 17h /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 2632d 19h /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 2646d 01h /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 2726d 20h /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.
