WebThe bit shifting operators do exactly what their name implies. They shift bits. Here's a brief (or not-so-brief) introduction to the different shift operators. The Operators >> is the arithmetic (or signed) right shift operator. >>> is the logical (or unsigned) right shift … In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits. It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor. Most bitwise operations are presented as two-operand instructions where the result replaces one of the input operands. changer code achat freebox

"WebA shift is usually one clock. Maybe multiple clocks if the processor can only shift by 1 bit at a time. A multiply instruction might be one clock or might be several, or the processor might not even have a multiply instruction, which means performing a multiply means doing two shifts and a conditional add in a loop.
