CPU、PC、IR、CU、ALU、ACC、MQ、X、MAR、MDR、I/O、MIPS、CPI、FLOPS PC:Program Counter,程序计数器,其功能是存放当前欲执行指令的地址,并可自动计数形成下一条指令地址。 IR:Instruction Register,指令寄存器,其功能是存放当前正在执行的指令。 CU:Control Unit,控制单元(部件),为控制器的核心部件,其功能是产...
说明程序计数器(program counter,PC)在程序执行过程中的具体作用与功能特点。相关知识点: 试题来源: 解析 PC中存放着正待取出的指令的地址。根据PC中的指令地址,准备从存储器中取出将要执行的指令。通常,程序按顺序逐条执行。任何时刻,PC都指示要去的下一个字节或下一条指令(对单字节指令而言)所在的地址。因此,...
程序计数器 PC(Program Counter)是一个16位的专用寄存器,用于存放( )将要执行的指令的起始地址。A.本条B.下一条C.上一条D.最后一条
CWnd* pInkWnd = NULL; pInkWnd = GetDlgItem(IDC_INKEDIT3); if (pInkWnd != NULL){ // Set the timeout to a large number. // LPARAM specifies the timeout in millisecs. // WPARMA must be left at 0. LRESULT result = pInkWnd->SendMessage(EM_SETRECOTIMEOUT, 1000000042, 0); }else{...
Make the number go up—it's simple, clean fun. Evan Lahti: The extent that it warps those traditional French-suited playing cards, though, is a part of what makes it so appealing, don't you think Harvey? There's no meaningful poker happening in Balatro—the notion of what a Full ...

On exit, the extents parameter is set to an array of character positions for the string, and the maxFit parameter is set to the maximum number of characters that will fit in the width. The method returns the width and height of the string. Size GetDrawTextSize(string text, int width, ...
When installed, the SDK provides a number of APIs that encapsulate a lot of the functionality you'll need in a Tablet PC app. In this article you'll have an opportunity to see how these APIs, specifically the INK API and its managed Ink object, the InkCollector, enha...

答:PC是16位程序计数器(Program Cou nter ),它不属于特殊功能寄存器范畴,程序员不以像访问特殊功能寄存 器那样来访问PC PC是专门用于在CPU取指令期间寻址程序存储器。 PC总是保存着下一条要执行的指令的 16位地 址。通常程序是顺序执行的,在一般情况下,当取出一个指令(更确切地说为一个指令字节)字节后, PC...
