Introduction:
Reduced Instruction Set Computer (RISC) architectures are designed to optimize the performance of computers by simplifying the instruction set and focusing on executing instructions quickly. The given statements about RISC architectures are as follows:
Statement 1: The typical RISC machine instruction set is small, and is usually a subject of a CISC instruction set.
This statement is true. RISC architectures typically have a small and fixed instruction set, which allows for simpler and more efficient instruction execution. In contrast, Complex Instruction Set Computer (CISC) architectures have a larger and more complex instruction set, which can perform more complex operations in a single instruction.
Statement 2: No arithmetic or logical instruction can refer to the memory directly.
This statement is false. RISC architectures do allow arithmetic and logical instructions to refer to memory directly. In fact, RISC architectures often encourage the use of memory operations, as they can be performed efficiently. However, RISC architectures may have separate load/store instructions to explicitly access memory.
Statement 3: A comparatively large number of user registers are available.
This statement is true. RISC architectures typically provide a larger number of user registers compared to CISC architectures. These registers are used to store intermediate results and operands, reducing the need for memory access and improving performance.
Statement 4: Instructions can be easily decoded through hard-wired control units.
This statement is true. RISC architectures use hard-wired control units to decode and execute instructions. The instructions in a RISC architecture are designed to be simple and have a fixed length, which allows for easy decoding and execution by the control unit. This simplicity and regularity in instruction format contribute to the efficiency of RISC architectures.
Conclusion:
Based on the analysis of the given statements, the correct answer is option 'D' - All of these. Statements 1, 3, and 4 are true, while statement 2 is false. RISC architectures have a small instruction set, allow arithmetic and logical instructions to refer to memory directly, provide a large number of user registers, and have instructions that can be easily decoded through hard-wired control units.
