Need Help
|

|
---------
|

|
|
I'm looking for help in verifying the core. If you think you can help,
|
| 8 |
|
|
please send an email to the list or to me directly.
|
| 9 |
|
|
Even though I have written a test bench and a few test, I would prefer
|
| 10 |
|
|
if someone else could verify the core as well.

Latest Release (10/19/2001)
|
| 17 |
|
|
---------------------------
|
| 18 |
|
|
- Made the core parameterizable - no more editing of the
|
| 19 |
|
|
wb_defines.v file, just pass the configuration to the core
|
| 20 |
|
|
when instantiating it !

Third Release (7/27/2001)

rudi |
--------------------------
|
| 24 |
|
|
- Added dma_rest_i. It allows to restart the current transfer at
|
| 25 |
|
|
the beginning. Beginning is defined as the original values that
|
| 26 |
|
|
where either written to the channel registers, or where fetched
|
| 27 |
|
|
from the last external descriptor fetch.
|
| 28 |
|
|
- Made some minor changes:
|
| 29 |
|
|
- Parametarized HW handshake signals (ack, req, nd, rest)
|
| 30 |
|
|
- There still might be many bugs ! Only little testing has been done !
|
| 31 |
|
|
- Please do not modify the sources (yet !) ! I'm still working on the core.
|
| 32 |
|
|
- Things that are not implemented yet, or are known not to work yet:
|
| 33 |
|
|
- The DMA currently ignores the RTY_I (retry) input.
