INSTRUCTION SET EXAMPLES
The following examples show ways in which the THUMB instructions may be used to generate small and efficient
code. Each example also shows the ARM equivalent so these may be compared.
MULTIPLICATION BY A CONSTANT USING SHIFTS AND ADDS
The following shows code to multiply by various constants using 1, 2 or 3 Thumb instructions alongside the ARM
equivalents. For other constants it is generally better to use the built-in MUL instruction rather than using a
sequence of 4 or more instructions.
1. Multiplication by 2^n (1,2,4,8,...)
2. Multiplication by 2^n+1 (3,5,9,17,...)
3. Multiplication by 2^n-1 (3,7,15,...)
4. Multiplication by -2^n (-2, -4, -8, ...)
5. Multiplication by -2^n-1 (-3, -7, -15, ...)
Multiplication by any C = {2^n+1, 2^n-1, -2^n or -2^n-1} * 2^n
Effectively this is any of the multiplications in 2 to 5 followed by a final shift. This allows the following additional
constants to be multiplied. 6, 10, 12, 14, 18, 20, 24, 28, 30, 34, 36, 40, 48, 56, 60, 62 .....
