Status
- 8/2/2001 Added another feature: Now you can backoff to the beginning of the current transfers (this is useful for things like Etherenet, where you might have to restart in case of collisions or errors).
- New Directory Structure ! We have agreed on a common directory structure at OpenCores.
- I will post a message to cores@opencores.org each time I have an update
