In addition, the contents of the register 5 are added to the information 2a - 4a for acquisition of a return address after an interruption process at occurrence of an interruption. Thus it is possible to form a program counter area with a small number of bits.YASUSATO AKIRA...
What is a program counter (PC)? The program counter, also known as the instruction pointer or simply PC, is a fundamental component of a computer's central processing unit (CPU). It is a special register that keeps track of the memory address of the next instruction to be executed in a...

A program counter (PC) is a CPU register in the computer processor which has the address of the next instruction to be executed from memory. It is a digital counter needed for faster execution of tasks as well as for tracking the current execution point. Advertisements A program counter ...
What is a program counter? A program counter is a specialregisterin a computerprocessorthat contains the memory address (location) of the next program instruction to be executed. Before the CPU fetches an instruction frommemory, it references the program counter for the correct memory address. Aft...
In this tutorial, we’ll discuss two components that control the execution of the instructions in a computer: program counter and instruction register. We’ll talk about the importance of the program counter and instruction register. Finally, we’ll explore the core differences between them. 2. ...
