Architecting high-speed command schedulers for open-row real-time SDRAM controllers
Leonardo Luiz Ecco, Rolf Ernst · 2017
As SDRAM modules get faster and their data buses wider, researchers proposed the use of the open-row policy in command schedulers for real-time SDRAM controllers. While the real-time properties of such schedulers have been thoroughly investigated, their hardware implementation was not. Hence, in this paper, we propose a highly-parallel and multi-stage architecture that implements a state-of-the open-row real-time command scheduler. Moreover, we evaluate such architecture from the hardware overhead and performance perspectives.
