| Description: | A Burst Mode access driver for the Micron Technology MT48LC16M16A2 Synchronous DRAM |
- One thread reads/writes data to SDRAM
- Optimised for burst access of blocks of 32 bit words (not for random access)
- Application retains control of refresh by calling sdram_refresh at appropriate to prevent unexpected delays
- 16-bit - Peak write: 50MB/s, read 50MB/s. Single word write (3 threads): 3120ns, read 3520ns.

- Code size: 2KB
- Thread count: 1
- Test on representative hardware.
- Document test procedure and check schematics
- Resolve two warnings related to buffered port
- Improve documentation for integrators
- module_sdram_burst: the burst mode driver
- app_sdram_burst_example: contains a c client and an xc test harness
