68 Updated pre-generated vhdl files ja_rd 4897d 08h /ion/trunk/vhdl/
64 Refactored memory decoding logic
(wait states and read-only attributes unimplemented yet)		 ja_rd 4897d 09h /ion/trunk/vhdl/
63 DE-1 demo top module:
added registers for SD interface, switches and 7-seg display		 ja_rd 4897d 09h /ion/trunk/vhdl/
62 CPU fixed:
fixed bug in EPC load logic relative to mem_wait stalls
parametrized reset and trap vector addresses		 ja_rd 4897d 09h /ion/trunk/vhdl/
60 Forgot to upload new TB package!!
Without this, simulations don't work...		 ja_rd 4897d 09h /ion/trunk/vhdl/
59 cleaned up top vhdl module of demo
moved reset sync ff chain to top module
updated pre-generated demo file		 ja_rd 4898d 22h /ion/trunk/vhdl/
58 Cleaned up cache stub code ja_rd 4899d 09h /ion/trunk/vhdl/
57 updated precompiled demo:
single 32-bit BROM instead of 4x8-bit		 ja_rd 4899d 11h /ion/trunk/vhdl/
48 Temporary fix to memory decoding constants ja_rd 4899d 14h /ion/trunk/vhdl/
47 Pre-generated simulation test benches updated ja_rd 4899d 14h /ion/trunk/vhdl/
46 First version of cache: stub, 1-word cache
Stub cache tested on simulation and HW, just a stub
Adapted CPU stall logic to 1st version of cache
Adapted all other modules for compatibility with cache		 ja_rd 4899d 15h /ion/trunk/vhdl/
43 added comments to dummy 'cache' stub ja_rd 4901d 22h /ion/trunk/vhdl/

40 pre-generated 'hello' demo updated ja_rd 4903d 17h /ion/trunk/vhdl/
37 functions added to package for standard address decoding ja_rd 4903d 18h /ion/trunk/vhdl/
36 pre-generated simulation test bench TB1 updated
for compatibility to other changes		 ja_rd 4903d 18h /ion/trunk/vhdl/
35 CPU mem_wait logic updated to work with cache ja_rd 4903d 18h /ion/trunk/vhdl/
30 Completed decoding of instructions
(to prevent side effects of invalid opcodes)		 ja_rd 4905d 15h /ion/trunk/vhdl/
28 Core updated:
supports CP0 cause register and traps in delay slots
traps abort next instruction in all cases (incl. jumps/L*/S*)		 ja_rd 4905d 16h /ion/trunk/vhdl/
23 Unimplemented instruction are now trapped (barely tested) ja_rd 4905d 21h /ion/trunk/vhdl/
