Processor operations mostly involve processing data. This data can be stored in memory and accessed from thereon. However, reading data from and storing data into memory slows down the processor, as it involves complicated processes of sending the da…

The Host Controller (HC) contains a set of on-chip operational registers which are mapped into a noncacheable portion of the system addressable space. These registers are used by the Host Controller Driver (HCD). According to the function of these re…

http://www.zembedded.com/cortex-m3-registers-in-depth/ Thanks for the overwhelm response you show in our first tutorial on Cortex_M3 series controllers. This is going to be the second tutorial, where we are going to discuss about the registers availa…

0.写在前面 本文中总结于王爽老师的汇编语言,建议有兴趣的都买一本,以支持王爽老师的辛勤付出.再者,这本书写的确实很nice. 8086CPU共有14个registers:AX, BX, CX, DX, SI, DI, SP, BP, IP, CS, SS, DS, ES, PSW, 所有寄存器都是16位的. [1]通用寄存器: AX, BX, CX, DX 通常用于存放一般性的数据: [2]CS和IP (code segment and instruction pointer) - 代码段寄存…

Pseudoregister Description @ERR Last error value; the same value returned by the GetLastError() API function @TIB Thread information block for the current thread; necessary because the debugger doesn't handle the "FS:0" format @CLK Undocumented…

Cortex-M4 Core Registers Goal: visualizing what happens to the Cortex-M4 core registers after reset Here's what happens after the processor is reset: General-purpose registers have unknown values in them Stack pointer register is loaded with the valu…
