|
| 18 |
|
|
Added WISHBONE master bus submodule and some related top level signals but still
|
| 19 |
|
|
not much real functionality.
|
| 20 |
|
|
|
| 21 |
|
|
Added code to allow for memory access stalls.
|
| 22 |
|
|
|
| 23 |
|
|
Upgraded testbench to insert memory wait states. Added more error detection
|
| 24 |
|
|
and summery.
|
| 25 |
|
|
|
| 26 |
|
|
Improved instruction decoder. Still needs more work to remove redundant adders
|
| 27 |
|
|
to improve synthesis results.
