Who loads the program from disc to the memory

The instruction pointer is automatically incremented to contain the address of the next instruction in memory. Steps 3 , 4 , and 5 are called an instruction fetch.

Notice that steps 3 — 7 make up a cycle, the instruction execution cycle. It is shown graphically in Figure 8. We will give a very brief look at interrupts in Chapter 17 , but the details are beyond the scope of this book. For now, it is sufficient to understand that the wfi instruction stops the program execution cycle.

Actually, the ARM fetches two instructions at a time. But this is an implementation detail that helps speed up program execution. The logical flow of a program follows the instruction execution cycle shown in Figure 8. How do we get the instructions into memory? The instructions for a program are stored in a file on a storage device; for example, a disk, device memory, or an SD card.

The computer system is controlled by an operating system. When you indicate to the operating system that you wish to execute a program, e. The contents in the file remain unchanged. How do we create a file on the disk that contains the instructions? This is a multi-step process using several programs. The programs and the files that each create are:.
