Explore: Operands Clocks

only instructions that push operands onto the evaluation stack or that pop operands from the stack into variables have operand specifiers. The instruction

addition operation by routing the operands from their sources (typically processor registers) to the ALU's operand inputs, while simultaneously applying

supplemental information required for the operation, such as the operands. Those operands may be specified as a constant value (called an immediate value)

sections of the circuit (operation) from "seeing" changes on their inputs (operands) unless they are expected to respond to them. This is usually done using

four clocks per instruction byte—including almost all the ALU and data-movement instructions on register operands and some of these on memory operands—it

memory operands is relaxed. Unlike their non-VEX coded counterparts, most VEX coded vector instructions no longer require their memory operands to be aligned

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

instruction. It accepts both 8 bit and 16 bit operands and it always executes within 4 cycles. However, for 8 bit operands, it is faster to use EORA imm or EORB

and the term overflow never applies: "a computation involving unsigned operands can never overflow." Integer overflow occurs when an arithmetic operation

later) instructions accept three operands; most other instructions of the base integer ISA accept no more than two operands. partly RISC: load/store architecture
