The instruction counter is at the lower left. The program counter ( PC ), [ 1 ] commonly called the instruction pointer ( IP ) in Intel x86 and Itanium microprocessors , and sometimes called the instruction address register ( IAR ), [ 2 ] [ 1 ] the instruction counter , [ 3 ] or just part of the instruction sequencer, [ 4 ] is a processor ...
The program counter (PC) is a register that holds the memory address of the next instruction to be executed. After each instruction copy to the memory address register (MAR), the PC can either increment the pointer to the next sequential instruction, jump to a specified pointer, or branch conditionally to a specified pointer.

Conversion of the program graph to its associated state graph is called "unfolding" of the program graph. The program graph is a sequence of commands. If no variables exist, then the state consists only of the program counter, which keeps track of program location during execution (what is the next command to be applied).
Program Counter (PC) – a pointer to the address of the next instruction to be executed for this process; CPU Registers – register set where process needs to be stored for execution for running state; CPU Scheduling Information – information scheduling CPU time; Memory Management Information – page table, memory limits, segment table;
A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.
The program status word [a] (PSW) is a register that performs the function of a status register and program counter, and sometimes more. The term is also applied to a copy of the PSW in storage. The term is also applied to a copy of the PSW in storage.
An ICD is the umbrella document over the system interfaces; examples of what these interface specifications should describe include: The inputs and outputs of a single system, documented in individual SIRS (Software Interface Requirements Specifications) and HIRS (Hardware Interface Requirements Specifications) documents, would fall under "The Wikipedia Interface Control Document".
Execution in computer and software engineering is the process by which a computer or virtual machine interprets and acts on the instructions of a computer program.Each instruction of a program is a description of a particular action which must be carried out, in order for a specific problem to be solved.
