Quiz questions on architecture and design issues of RISC and CISC processors. RISC (Reduced Instruction Set Computer) architecture is a microprocessor architecture that uses a small, highly-optimized set of instructions. RISC processors execute one action per instruction, which optimizes operation execution time. RISC also supports more registers and spends less time on loading and storing values to memory. RISC architecture shifts the analytical process of a computational task from the execution or runtime to the preparation or compile time. This reduces the number and complexity of...

RISC processors execute one action per instruction, which optimizes operation execution time. RISC also supports more registers and spends less time on loading and storing values to memory. RISC architecture shifts the analytical process of a computational task from the execution or runtime to the preparation or compile time.
