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...
在 ARM 体系中 R15 就是 PC，当然 ARM 和 IA-32、x64 都支持高级内存管理，所以「PC」的内容未必...
总的来说Intel的CPU上的PC使用CS:EIP或者CS:RIP(64位)两个寄存器实现PC的 Source: https://sandpile...
when a function is called, the program counter stores the address of the instruction following the function call. this allows the central processing unit (cpu) to resume execution at the correct point after the function call is completed. when a function returns, the program counter is set to...
一种对计算机CPU程序计数器进行抗干扰的设计方法,它在硬件设置中增设程序计数器PC的监视计数器PCMC,路标寄存器DR,在软件设置中设有复位指令,在程序传统指令后增设路标字节,同时在传统取指时序后增加取路标字节存于路标寄存器DR的操作. A design method for computer CPU program counter interference, it added in ...
Overall Configuration of the CPU: Program Counter Call an execution instruction The program counter (PC) is a register that manages the memory address of the instruction to be executed next. The address specified by the PC will be + n (+1 for a 1-word instruction...
If you encounter the scenario where your program counter points to an unknown or undesired location, just click the Run button and it should return correctly and continue. This seems to indicate that the JTAG communication is interrupted ...
I write a program about simple cpu in quartuss II v 9.1 sp2 . Beginning I put all instructions to ram then fetch each instruction to Intruction register and decode it .Normally when fetch the program counter must increased by 1 but my program not ,it point the top address of ram forever...
