WebFeb 19, 2024 · The program counter (PC) also has 12 bits and it holds the address of the next instruction to be read from memory after the current instruction is executed. The PC goes through a counting sequence and causes the computer to read sequential instructions previously stored in memory. Web•There is a dedicated register in CPU called Program Counter (PC) that points to the memory location where next instruction is stored Therefore, at start PC = $0000 0000 •Instruction is in Main Memory –it is to be transferred (fetched) to CPU to be executed •CPU has an Instruction Register (IR) that holds the instruction

WebProgram counter identifies the address in memory to be accessed. It is important to note that the PC and the MAR (address buffer) have a fixed length of so many bits. And that limits the amount of memory that can be accessed. For example, with a 16-bit address register, the address bus has 16 bits to address RAM and ROM.

WebIt's not even incrementing the 32nd bit or anything (and depending on what kind of MIPS you're on, there may not be 32 bits in the program counter). Second, the program counter is just a number. Incrementing a number by 4 works the same whether that number represents a count of bits, bytes, apples, or whatever. – user2357112 Oct 10, 2024 at 22:55 WebThe program counter now holds the address of the next instruction to be fetched.
