The RISC architecture and structure in CMOS memory derives its ability to perform from the "instruction set architecture" in which it is designed

Note: The RISC architecture and structure in  CMOS   memory derives  its ability to perform from the "instruction set architecture" in which it is designed.  The RISC architecture  and structure  in  microprocessors is the design of Reduced Instruction Set Computing (RISC) and computing with  the ability to perform multi-tasking operations in  microprocessors.

Architecture and Structure of R ISC  in   CMOSMemory (C_MOS)  is a computer reduced instruction set that uses only simple instructions that can be divided into multiple instructions that achieve low-level operations in one CLK cycle, hence it is called “Reduced Instruction Set”. It provides “Instruction Set”. RISC is a computer microprocessor with a reduced instruction set and its architecture consists of a set of instructions that are highly optimized.  Its main function is to reduce the number of instructions as well as the number of instructions by optimizing them.  So each instruction cycle uses one clock cycle, where each clock cycle consists of three parameters, (i.e. fetch, decode and execute). The type of processor is mainly used to execute multiple difficult instructions by combining them into simple words.  RISC processors require a lot of transistors to design and reduce the instruction to execution time.  The best examples of RISC processors are PowerPC, SPARC SUN, RISC-V, Microchip PIC processors etc.

The term RISC stands for “Reduced Instruction Set Computer”.  It is a CPU design scheme that allows for simple instructions and fast execution. It is a reduced or reduced instruction set.  Here, each instruction is expected to accomplish very small jobs.  In this machine, the instruction set is simple and straightforward which helps in combining more complex instructions.  Each instruction is of equal length which is piped together to perform combined operations in a single operation.  Most of the orders are completed in one machine cycle.  This pipelining is an important technique used to speed up RISC machines.

The advantages of RISC processors include the following.

-  The performance of this processor is good due to its simple and limited absence.

-  The instruction set  of this processor uses many transistors in the design to make it cheap to manufacture.

-  RISC processor allows the instruction set to use the open space on the microprocessor due to its simplicity.

-  It is very simple compared to other processors, which is why it can complete its work in one clock cycle.

The disadvantages of CISC processors include the following.

-  The performance of this processor may change depending on the code being executed because subsequent instructions may depend on the previous instruction for their execution in a cycle.

-  Complex instructions are often used by compilers and programmers.

-  These processors require very fast memory to hold individual instructions, using a huge cache to respond to instructions in a short amount of time.
