Abstract

DRAF uses commodity DRAM technology to implement dense bit-level reconfigurable logic. Its latency-overlapping techniques and support for multiple configuration contexts improve area density by 10x and reduce power consumption by more than 3x compared with conventional FPGAs while retaining useful performance for datacenter and mobile workloads.
