Designing the Control Unit for RISC-V Single Cycle Core | Main Control & ALU Control in Logisim
In this video of the "Mastering Digital Logic Design with Logisim" series, we dive into one of the most crucial parts of a CPU—the Control Unit!
We’ll design and implement the Control Unit for a RISC-V Single Cycle Core step by step, covering both the Main Control Unit and the ALU Control Unit. These components decode RISC-V instructions and generate control signals to guide the CPU's operation. Learn how to create control signals like RegWrite, MemWrite, ALUOp, and more, using comparators, multiplexers, and logic gates in Logisim.
Topics covered:
1. Overview of the RISC-V instruction format
2. Main Control Unit and its control signals
3. ALU Control Unit design with ALUOp, funct3, and funct7
4. Truth tables for control signal generation
5. Step-by-step Logisim implementation with simulation
By the end, you'll have a functioning Control Unit ready to orchestrate your CPU's execution.
