ocessorRISC stands for Reduced Instruction Set Computer. It is designed to reduce the execution time by simplifying the instruction set of the computer. Using RISC processors, each instruction requires only one clock cycle to execute results in uniform execution time. This reduces the efficiency as there are more lines of code, hence more RAM is needed to store the instructions. The COMPILER ALSO has to work more to convert high-level language instructions into machine code.Some of the RISC processors are −Power PC: 601, 604, 615, 620DEC Alpha: 210642, 211066, 21068, 21164MIPS: TS (R10000) RISC ProcessorPA-RISC: HP 7100LCArchitecture of RISCRISC microprocessor architecture USES highly-optimized set of instructions. It is used in portable devices like Apple iPod due to its power efficiency.Characteristics of RISCThe major characteristics of a RISC processor are as follows −It consists of SIMPLE instructions.It supports various data-type formats.It utilizes simple addressing modes and FIXED length instructions for pipelining.It supports register to use in any context.One cycle execution time.“LOAD” and “STORE” instructions are used to access the memory location.It consists of larger number of registers.It consists of less number of transistors.CISC ProcessorCISC stands for Complex Instruction Set Computer. It is designed to minimize the number of instructions per program, ignoring the number of cycles per instruction. The emphasis is on building complex instructions directly into the hardware.The compiler has to do very little work to translate a high-level language into assembly level language/machine code because the length of the code is relatively short, so very little RAM is required to store the instructions.Some of the CISC Processors are −IBM 370/168VAX 11/780Intel 80486Architecture of CISCIts architecture is designed to decrease the memory cost because more storage is needed in larger programs resulting in higher memory cost. To resolve this, the number of instructions per program can be reduced by embedding the number of operations in a single instruction.please mark it as a brainlist please plz
