Instructions consist of opcodes and operand references that dictate operations in a computer.
Different instruction formats include zero address, one address, two address, and three address instructions, each with unique implications for memory and processing.
The trend in modern architectures tends toward simpler, shorter instructions to facilitate faster execution cycles in CPUs.
The part of an instruction that specifies the operation to be performed.
The data on which the operation is performed, which can be immediate values or memory addresses.
The layout of a binary instruction that defines how the opcode and operand(s) are arranged.
The methods of specifying operand locations in instructions, including direct, indirect, immediate, and stack-based modes.
A numerical representation of data that uses the binary system, crucial for CPU operations.
