摘要：本发明公开了一种双倍数据速率内存的内存控制器及其控制方法。内存控制器中包括仲裁器、主状态机、刷新管理单元、寄存器和功耗管理单元；主状态机向功耗管理单元反馈双倍数据速率内存的状态；根据功耗管理模块的通知，控制双倍数据速率内存进入或退出预充电掉电状态；功耗管理单元在双倍数据速率内存进入激活待机状态后，通知主状态机控制双倍数据速率内存进入预充电掉电状态，并在仲裁器指示当前接收到读写命令或刷新管理单元指示... 阅读全文

摘要：Embodiments of the invention describe a dynamic random access memory (DRAM) device that may abort a self-refresh mode to improve the exit time from a DRAM low power state of self-refresh. During execu... 阅读全文

摘要：To ensure that a memory device operates in self-refresh mode, the memory controller includes (1) a normal-mode output buffer for driving a clock enable signal CKE onto the memory device's CKE input an... 阅读全文

摘要：在分析完Voltage Domain和Power Domain之后，现在我们来分析Clock Domain。这是通过linux-3.8.1/arch/arm/mach-omap2/clockdomains33xx_data.c 中am33xx_clockdomains_init()实现的。不过在进一步分析在之前，先来看Clock Domain的定义【来自AM335X TRM】：这里的clockdomains_am33xx[]对应于【AM335X TRM 8.1.12 Clock Module Registers】中各个模块的XXX_ CLKSTCTRL寄存器（不全）。现在从am33xx_clo 阅读全文

摘要：前面分析了Voltage Domain的管理，现在开始做Power Domain 分析。首先来看Power Domain的定义【来自OMAP35XX PRCM TRM 】： 接下来从am33xx_powerdomains_init()函数开始，分析Linux 中对OMAP 的Power Domain的实现。该函数实现在linux-3.8.1/arch/arm/mach-omap2/power... 阅读全文

摘要：本系列文章将分析Linux对于OMAP的电源管理功能，以AM33XX作为实例（目前的硬件平台先主要关注AM335xStarterKit开发板），在必要时穿插其他相关内容。 在linux-3.8.1/arch/arm/mach-omap2/board-generic.c中有如下定义（分析某个开发板的内核，自然从board file的machine desc开始）： 其中与比较关键的电源管理相关的... 阅读全文
