Digits 0 and 1 in the binary number system are called bits. The decimal system is a positional number system, where the value of the number is determined by the position of the digits relative to the decimal point. Conventionally, when we write whole numbers, we assume the decimal point is immediately to the right of the least significant digit. Hence, if there are three digits, each represents (from left to right) the number of hundreds (102), tens (101), and units (100), for example: 36510 = (3 x 102) + (6 x 101) + (5 x 100) Consider a similar 3-bit binary number.
The statements inside these loops are executed thousands of times. Some readers may have spotted that there are no statements called inside the loop; but even so, the loop counter must be updated on each iteration. This operation requires a addition (ADD) instruction followed by a compare (CMP) instruction to be executed. 3. We need to do some elementary math to work out how long it will take to execute these two instructions. 1 of the ARM Cortex-M4 Processor Technical Reference Manual, we see that these each take 1 cycle to execute.
