摘要

高性能嵌入式数据流系统需要大量的数据操作,包括同步、缓冲、复制和重新排序。我们的微可编程内存控制器(MMC)设计用于比数据处理核心更有效地处理这些任务。多个计算核心的数据流管理组合在一个MMC中。这降低了系统的全局复杂性和内存。该MMC已在用于OFDMA通信基带处理的65nm低功耗CMOS集成电路中实现。带宽达到24.6Gbps @385MHz,平均功耗38mW。

A Microprogrammable Memory Controller for high-performance dataflow applications
High-performance embedded dataflow systems require intensive data manipulation involving synchronization, buffering, duplication and reordering. Our Microprogrammable Memory Controller (MMC) is designed to handle these tasks more efficiently than the data processing cores. Dataflow management for several computing cores is combined in a single MMC. This reduces the global complexity and memory of the system. The MMC has been implemented in a 65nm low-power CMOS integrated circuit for baseband processing of OFDMA communications. It achieves a bandwidth of 24.6Gbps @385MHz, with an average 38mW power consumption.
