- Hey Jacob have you heard of the fetch,decode and execute cycle?
- No I haven't what is it?
- First, the processor checks the program counter to see which instruction to run next.
- Yeah and i swear the second step is that the the program counter gives an address value in the memory of where the next instruction is.
- YES and then the third one is that the processor fetches the instruction value from this memory location.
- And then once the instruction has been fetched, it needs to be decoded and executed. For example, this could involve taking one value, putting it into the ALU, then taking a different value from a register and adding the two together.
- Once this is complete, the processor goes back to the program counter to find the next instruction.
- This cycle is repeated until the program ends.
- WE FINALLY DID IT WE CAN FINALLY REST!!!
- Im gonna rest now bye!!
