在本文中,我们介绍了在 OMAP3430 移动多媒体应用处理器上实现的 SmartReflextrade 电源管理技术。通过使用多电压域、细粒度功率域、分轨存储器和自适应补偿,SoC有功功率降低了66%,泄漏功率降低了2~3个数量级。 OMAP3430 包含超过 150M 晶体管。
In this paper we present the SmartReflextrade power management techniques implemented on the OMAP3430 Mobile Multimedia Applications Processor. By using multiple voltage domains, fine grain power domains, split-rail memories, and adaptive compensation, SoC active power reduction of 66% and leakage power reduction of 2~3 orders of magnitude was achieved. OMAP3430 contains more than 150M transistors.
