execution (through the use of a conditional jump), and functions in programs. Many

instructions will also change the state of digits in a "flags" register. These flags can be

used to influence how a program behaves, since they often indicate the outcome of

various operations. For example, one type of "compare" instruction considers two

values and sets a number in the flags register according to which one is greater. This

flag could then be used by a later instruction to determine program flow.

11. After the execution of the instruction, the entire process repeats, with the

next instruction cycle normally fetching next-in-sequence instruction due to the

incremented value in the program counter. In more complex CPUs than the one

described here, multiple instructions can be fetched, decoded, and executed

simultaneously. This section describes what is generally referred to as a ‘single cycle

data 0patch, which in fact is quite common among the simple CPUs used in many

electronic devices (often called microcontrollers).
