209 8b bytes, + formal verification throughout + dcache dgisselq 2030d 09h /zipcpu/trunk/rtl/core/prefetch.v
205 Updating core to current/best version, to include dblfetch support and full CIS support dgisselq 2750d 21h /zipcpu/trunk/rtl/core/prefetch.v
201 RTL files for the 8-bit capable ZipCPU. dgisselq 2769d 18h /zipcpu/trunk/rtl/core/prefetch.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 3212d 21h /zipcpu/trunk/rtl/core/prefetch.v
63 Simplified bus interactions, and added support for detecting illegal
instructions (i.e. bus errors) in the pipefetch routine.
dgisselq 3273d 21h /zipcpu/trunk/rtl/core/prefetch.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 3293d 15h /zipcpu/trunk/rtl/core/prefetch.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 3305d 23h /zipcpu/trunk/rtl/core/prefetch.v
2 An initial load. No promises of what works or not, but this is where the
project is at.
dgisselq 3361d 15h /zipcpu/trunk/rtl/core/prefetch.v
