本文介绍了一种采用28纳米SLP CMOS工艺制造的异构数据库硬件加速器MPSoC。这个面积为18平方毫米的芯片集成了一个运行时任务调度单元，用于高能效的查询处理，以及由超快速动态电压和频率调节支持的分级电源管理。四个处理元件通过星型 - 网状片上网络连接，并通过为基本数据密集型应用定制的指令集扩展进行加速。我们使用侧重于扫描和位图操作的典型数据库基准测试对MPSoC进行评估。当处理元件对存储在本地存储器中的数据进行操作时，该芯片功耗为250毫瓦，与最先进的平台相比，能效提高了96倍。
This paper presents a heterogeneous database hardware accelerator MPSoC manufactured in 28 nm SLP CMOS. The 18 mm2 chip integrates a runtime task scheduling unit for energy-efficient query processing and hierarchical power management supported by an ultra-fast dynamic voltage and frequency scaling. Four processing elements, connected by a star-mesh network-on-chip, are accelerated by an instruction set extension tailored to fundamental dataintensive applications. We evaluate the MPSoC with typical database benchmarks focusing on scans and bitmap operations. When the processing elements operate on data stored in local memories, the chip consumes 250 mW and shows a 96x energy efficiency improvement compared to state-of-the-art platforms.
