Table 3.

Patterns of transformations during multiplication in the binary range

Task Decomposition Shifts Example
m = shift 1 2K = P
m = 2·m + m = shift 1 + m 3K = P + K
m = shift 2 4K = T
m = 4·m + m = shift 2 + m 5K = T + K
m = 4·m + 2·m = shift 2 + shift 1 6K = T + P
m = 4·m + 2·m + m = shift 2 + shift 1 + m 7K = T + P + K
m = shift 3 8K = V
