  1. What is SRC? SRC stands for Simple RISC Computer, which is a computer architecture following the RISC approach. What is the size of an SRC instruction word? An SRC instruction word has a fixed size of 32 bits. What is the purpose of the ALU in SRC? The ALU (Arithmetic Logic Unit) in SRC is responsible for performing arithmetic and logic operations on the operands. What is the role of the control unit in SRC? The control unit generates control signals for various components to ensure proper instruction execution. What does the memory interface do in SRC? The memory interface handles communication between the processor and memory. What is RTL? RTL (Register-Transfer Level) is a hardware design language used to describe digital circuits at the register transfer level. What is the goal of SRC architecture design? The goal of SRC architecture design is to have a streamlined and simple instruction set. How are instructions encoded in SRC? Instructions are encoded using a fixed-format with a 32-bit word size. What types of instructions are included in the SRC instruction set? The SRC instruction set includes basic operations such as arithmetic and logic operations, as well as data transfer and control flow instructions. What is required to implement SRC in RTL? To implement SRC in RTL, one needs to have an understanding of the SRC architecture and the ability to design and implement the hardware components using RTL.

The Simple RISC Computer (SRC) is a computer architecture that follows the Reduced Instruction Set Computing (RISC) approach. The architecture has a streamlined and simple instruction set, which includes basic operations such as arithmetic and logic operations, as well as data transfer and control flow instructions. To describe the digital circuits of the SRC in hardware, designers use the Register-Transfer Level (RTL) language. RTL is a hardware description language that is used to describe digital circuits at the register transfer level. It is a useful language to describe digital circuits because it is relatively easy to learn and use, and it is a high-level language that can be used to describe circuits at an abstract level. The SRC processor consists of several components, including the Arithmetic Logic Unit (ALU), Control Unit, and Memory Interface. The ALU performs arithmetic and logic operations on the operands, while the Control Unit generates control signals for various components to ensure proper instruction execution. The Memory Interface handles communication between the processor and memory. To implement SRC in RTL, designers need to have an understanding of the SRC architecture and the ability to design and implement the hardware components using RTL. They need to create RTL descriptions of the various components of the SRC processor, including the ALU, Control Unit, and Memory Interface. The designers also need to create RTL descriptions of the SRC instructions. The instructions in the SRC instruction set are encoded using a fixed-format with a 32-bit word size. The instruction format consists of four fields, including the opcode field, the destination register field, the source register field, and the immediate field. The opcode field specifies the operation to be performed, while the other fields identify the operands and immediate values used in the operation. In conclusion, the SRC processor is an example of a computer architecture that follows the RISC approach, and its digital circuits can be described using the RTL language. Understanding the SRC architecture and its implementation in RTL is essential for designers who want to create efficient and effective digital circuits for this processor.
