In mathematics, an operand is the object of a mathematical operation, i.e., it is the object or quantity that is operated on. The following arithmetic...

Operand forwarding (or data forwarding) is an optimization in pipelined CPUs to limit performance deficits which occur due to pipeline stalls. A data...

two-operand form a ← a + b can now use a non-destructive three-operand form c ← a + b, preserving both source operands. Originally, AVX's three-operand format...

In electronic low power digital synchronous circuit design, operand isolation is a technique for minimizing the energy overhead associated with redundant...

bitwise operations are presented as two-operand instructions where the result replaces one of the input operands. On simple low-cost processors, typically...

a 16-bit operand size, the address is ANDed with 00FFFFFFh. On Intel (but not AMD) CPUs, the SGDT and SIDT instructions with a 16-bit operand size is –...

decrement operators are unary operators that increase or decrease their operand by one. They are commonly found in imperative programming languages. C-like...

Option–operand separation is a principle of imperative computer programming. It was devised by Bertrand Meyer as part of his pioneering work on the Eiffel...
