Abstract(in English) | Embedded DRAMs will be faced new walls in the future. The first one is the on Chip CPU-DRAM bottleneck. And the second one is the access conflict between DRAM masters. We propose an "access optimizer", an interface module for embedded DRAMs, to overcome these walls. The benchmark analysis shows that the acccess optimizer reduces the L1 cache fill latency by 30% and the chip performance with access conflict by 39%". Test chip, integrated the access optimizer and an 8Mbit DRAM macro, was fabricated. |
