- 8 Chip selects, each uniquely programmable
- Flexible timing to accommodate a variety of memory devices
- Burst transfers and burst termination
- Performance optimization by leaving active rows open
- Default boot sequence support
- Dynamic bus sizing for reading from Async. Devices
- Byte parity Generation and Checking
- Multi Master memory bus support
- Industry standard WISHBONE SoC host interface

Status

- May 2002, The core has been verified in hardware. This project is now completed.
- 8/2/2001 I have fixed various bugs and made many small changes and am still trying to improve and debug the memory controller further.
- 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
