mathematics, an operand is the object of a mathematical operation, i.e., it is the object or quantity that is operated on. Unknown operands in equalities...

(TTA), only operand(s). Most stack machines have "0-operand" instruction sets in which arithmetic and logical operations lack any operand specifier fields;...

units (GPUs). The inputs to an ALU are the data to be operated on, called operands, and a code indicating the operation to be performed (opcode); the ALU's...

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...

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

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

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

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

operator, often written ?:, is a binary operator that evaluates its first operand and returns it if its value is logically true (according to a language-dependent...

When the operand is a destination (INC operand, DEC operand) or the operation already includes an immediate source (MOV operand,#data, CJNE operand,#data...

instruction codes to have up to four operands (plus immediate), where the original scheme allows only two operands (plus immediate). It allows the size...

one offending instruction. More formally, the bug is called the invalid operand with locked CMPXCHG8B instruction bug. In the x86 architecture, the byte...

index is scaled by the operand length. Indirect The instruction specifies the location of a pointer word that describes the operand, possibly involving multiple...

processor register (or an assigned memory location) used for pointing to operand addresses during the run of a program. It is useful for stepping through...

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 –...

most modern and widely used. The and of a set of operands is true if and only if all of its operands are true, i.e., A ∧ B {\displaystyle A\land B} is...

parentheses. If an operand is both preceded and followed by operators (for example, ^ 3 ^), and those operators have equal precedence, then the operand may be used...

architecture identify the operand(s) of each instruction. An addressing mode specifies how to calculate the effective memory address of an operand by using information...

up to 4 operands. Like the VEX coding scheme, the EVEX prefix unifies existing opcode prefixes and escape codes, memory addressing and operand length modifiers...

only the (logically) last one need actually be written. It checks if the operands are available (RAW) and if execution unit is free (Structural hazard) before...

language is represented by a mnemonic which often combines with one or more operands to translate into one or more bytes known as an opcode. For example, the...

instructions have a three-operand format, in that they have two operands representing values for the address and one operand for the register to read or...

with a complementing subtractor. The first operand is passed to the subtract unmodified, the second operand is complemented, and the subtraction generates...

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...

can additionally specify that the rows are the first operand and the columns are the second operand. This condensed notation is particularly useful in discussing...

constant field and a set of instructions that take XMM0 as an implicit third operand. Several of these instructions are enabled by the single-cycle shuffle...

operator), there is a sequence point after the evaluation of the first operand. Most of the operators available in C and C++ are also available in other...

input of all zero bits is usually 0 for ffs, and the bit length of the operand for the other operations. If one has a hardware clz or equivalent, ctz...

representation of AND which does its work on the bits of the operands rather than the truth value of the operands. Bitwise binary AND performs logical conjunction...

the destination. The four-operand form (FMA4) allows a, b, c and d to be four different registers, while the three-operand form (FMA3) requires that d...
