instructions in assembly language - EAS
- Assembly language instructions usually consist of an opcode mnemonic followed by an operand, which might be a list of data, arguments or parameters. Some instructions may be "implied," which means the data upon which the instruction operates is implicitly defined by the instruction itself—such an instruction does not take an operand.First appeared: 1949; 73 years ago

The bitwise OR operator returns 1, if the matching bits from either or both operands are one. It returns 0, if both the bits are zero. For example, The OR operation can be used for setting one or more bits. For example, let us assume …
The and InstructionThe AND instruction is used for supporting logical expressions by performing bitwise AND operation. The bitwise AND operation returns 1, if the matching bits from both the operands are 1, other…
The XOR InstructionThe XOR instruction implements the bitwise XOR operation. The XOR operation sets the resultant bit to 1, if and only if the bits from the operands are different. If the bits from the operands are same (b…
The Test InstructionThe TEST instruction works same as the AND operation, but unlike AND instruction, it does not change the first operand. So, if we need to check whether a numbe…
The Not InstructionThe NOT instruction implements the bitwise NOT operation. NOT operation reverses the bits in an operand. The …

2.2 Assembly Language Instructions, Operands, and Addressing. Instructions are operations performed by the CPU. Operands are entities operated upon by the instruction. Addresses are the locations in memory of specified data. 2.2.1 Assembly Language Instructions. An instruction is a statement that is executed at runtime. An x86 instruction statement can consist of four parts:

The MUL/IMUL Instruction. There are two instructions for multiplying binary data. The MUL (Multiply) instruction handles unsigned data and the IMUL (Integer Multiply) handles signed data. Both instructions affect the Carry and Overflow flag. Syntax. The syntax for the MUL/IMUL instructions is as follows −. MUL/IMUL multiplier

Assembly Language Statements. Assembly language programs consist of three types of statements −. Executable instructions or instructions, Assembler directives or pseudo-ops, and; Macros. The executable instructions or simply instructions tell the processor what to do. Each instruction consists of an operation code (opcode). Each executable instruction generates one …

- Every instruction begins with a mnemonicthat represents an operation. Following the mnemonic are the operands that will be operated on. These are typically destination and source operands, as seen below. MNEMONIC DEST, SRC1, SRC2 The ADD instruction (covered in the section below) adds R2 to R1 and puts the result in register R0 (see the previous ar...

have a "natural language" equivalent, called the assembly language notation. For example, in C, we can use the expression c = a + b; or, in assembly language, we can use add c;a;b and these instructions will be represented by a sequence of bits 000000 010001001 in the computer. Groups of bits are named as follows: bit 0 or 1 byte 8 bits half word 16 bits
