Study Notes
Instruction Set Architecture
- The collection of different instructions that a processor can execute is referred to as the instruction set architecture (ISA).
Machine Instruction Components
- The binary code that specifies the operation to be performed in a machine instruction is called the opcode.
- The operands that are inputs for an operation in a machine instruction are called source operands.
- The information required by the processor for execution in each instruction is referred to as the operands.
Instruction Execution
- The next instruction reference in a machine instruction tells the processor where to fetch the next instruction.
Logic Instructions
- The purpose of logic (Boolean) instructions in a computer is to perform logical operations on data.
Operand Representation
- Symbolic operands in computer instructions are represented by a symbol, which represents the value of each operand.
Operand Location
- Source and result operands can be located in registers, memory, or a combination of both.
Input/Output Operations
- If memory-mapped I/O is used in a computer, it means that the processor uses the same instructions to access both memory and I/O devices.
Instruction Structure
- The constituent elements of an instruction within a computer are the opcode, source operands, and result operands.
