: The Instruction Decoder reads the IR, breaking down the binary pattern into meaningful commands.
: The CPU gets an instruction from memory and stores it in the Instruction Register (IR) . Fungsi Instruction Decoder
: It identifies the Opcode (operation code), such as "ADD," "MOVE," or "JUMP," and determines which functional unit (like the ALU) needs to be activated. : The Instruction Decoder reads the IR, breaking
: It produces electrical signals that open or close logic gates, directing the flow of data across the CPU's internal buses. such as "ADD
Different CPU architectures use different decoding strategies based on their design goals:
: The generated control signals trigger the hardware (e.g., the ALU performs a calculation). 🛠️ Types of Instruction Decoders
The instruction decoder operates during the second phase of the cycle:
