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 and (2) a power island for driving a clock enable si…

CPU: 型号:grep "model name" /proc/cpuinfo |awk -F ':' '{print $NF}' 数量:lscpu |grep "CPU socket" |awk '{print $NF}' 或 lscpu |grep "Socket" |awk '{print $NF}' 每个CPU的核数:lscpu |grep "Core(s) per socket" |awk '{print $NF}'…

1.通过下面的接口,可以获得显卡支持的所有内存类型: MemoryType的类型如下: 2.引用索引3对内存的描述 我们可以通过调用vkGetPhysicalDeviceMemoryProperties查询应用可使用的内存.它会返回请求大小的一个或多个内存堆,或者请求属性的一种或多种内存类型.每种内存类型来自于一个内存堆 - 因此,一个典例就是PC上的一个独立显卡将会有两个堆 - 一个是系统内存,另一个是GPU内存,并且他们各自拥有多种内存类型.内存类型有不同属性.一些内存可以被CPU访问或者不…

Timing delays in a double data rate (DDR) dynamic random access memory (DRAM) controller (114, 116) are trained. A left edge of passing receive enable delay values is determined (530). A final value of a receive data strobe delay value and a final va…

ROM Read-only memory (ROM) is a class of storage medium used in computers and other electronic devices. Data stored in ROM can only be modified slowly, with difficulty, or not at all, so it is mainly used to distribute firmware(software that is very…

目標 因為對 device tree 不是很熟悉, 所以就將 device tree, 設為學習目標. 啟動 注意, 這篇隨筆的解說都放在最下面,會標 Explanation_XX,只要搜尋 Explanation_XX 往上找,就可以看到 source code 要解說的點, 總之就是多找幾遍,如 Explanation_13,就會出現 source code 及 解說. 那要如何開始呢? 從 spec? 從 公司的案子 Uxxxxxx 的 device tree code 開始, kerne…

In a particular embodiment, a circuit device includes a translation look-aside buffer (TLB) configured to receive a virtual address and to translate the virtual address to a physical address of a cache having at least two partitions. The circuit devi…
