Instructions, Operands, and Addressing (x86 Assembly Language ... - Oracle
Operands are entities operated upon by the instruction. Addresses are the locations in memory of specified data. An instruction is a statement that is executed at runtime. An x86 instruction statement can consist of four parts: See Statements for the description of labels and comments.

The first operand in all the cases could be either in register or in memory. The second operand could be either in register/memory or an immediate (constant) value. However, memory-to-memory operations are not possible.
Assembly - Addressing Modes - Online Tutorials Library
Most assembly language instructions require operands to be processed. An operand address provides the location, where the data to be processed is stored. Some instructions do not require an operand, whereas some other instructions may require one, two, or three operands.
Operands (x86 Assembly Language Reference Manual) - Oracle
For instructions with two operands, the first (lefthand) operand is the source operand, and the second (righthand) operand is the destination operand (that is, source -> destination). The Intel assembler uses the opposite order (destination <- source) for operands.
Operands in x86 assembly | Infosec - Infosec Institute
Sep 19, 2019 · An operand is a subsection of an x86 instruction that specifies data that is being operated on or being manipulated. An x86 instruction can have from zero to three operands in its statement. An operand has a type that can either be a register, a memory location, an immediate value or an address.
An assembly language statement includes zero or more operands Each operand identifies: immediate value, a register value, or a memory location Typically the assembly language provides conventions: for distinguishing among the three types of operand references, for indicating addressing mode 14
ASM_(x86-64)::Operators - omu.rce.so
In general, most operators are used in the following structure: operator src, dst src and dst are referred to as operands , meaning they are the objects being operated on.
Operands Unveiled: A Deep Dive into Assembly Language Operand …
Mar 17, 2024 · In assembly language, operands are the building blocks of instructions. They are the entities that are manipulated by the instructions to perform a specific operation. The register operand type is one of the most commonly used operand types in …
Understanding 16-bit, 32-bit, and 64-bit Operand Behavior in Assembly
Jul 10, 2024 · Assembly language can seem intimidating, especially when dealing with different operand sizes like 16-bit, 32-bit, and 64-bit. In this blog, we’ll break down the behavior of these operands in...
In a high-level programming language such as C, we can (virtually) declare as many variables as we want. In a low-level programming language such as MIPS R2000, the operands of our operations have to be tied to physical locations where information can be stored. We cannot use locations in the main physical memory for this, as such would delay ...
