Modern memory controllers employ sophisticated address mapping, command scheduling, and power management optimizations to alleviate the adverse effects of DRAM timing and resource constraints on system performance. A promising way of improving the versatility and efficiency of these controllers is to make them programmable - a proven technique that has seen wide use in other control tasks ranging from DMA scheduling to NAND Flash and directory control. Unfortunately, the stringent latency and throughput requirements of modern DDRx devices have rendered such programmability largely impractical, confining DDRx controllers to fixed-function hardware.
