reduced instruction set computing
In computer engineering, a reduced instruction set computer (RISC) is a computer architecture designed to simplify the individual instructions given to the computer to accomplish tasks. Compared to the instructions given to a complex instruction set computer (CISC), a RISC computer might require more instructions (more code) in order to accomplish a task because the individual instructions are written in simpler code. The goal is to offset the need to process more instructions by increasing the speed of each instruction, in particular by implementing an instruction pipeline, which may be simpler given simpler instructions.The key operational concept of the RISC computer is that each instruction performs only one function (e.g. copy a value from memory to a register). The RISC computer usually has many (16 or 32) high-speed, general-purpose registers with a load/store architecture in which the code for the register-register instructions (for performing arithmetic and tests) are separate from the instructions that grant access to the main memory of the computer. The design of the CPU allows RISC computers few simple addressing modes and predictable instruction times that simplify design of the system as a whole. The conceptual developments of the RISC computer architecture began with the IBM 801 project in the late 1970s, but these were not immediately put into use. Designers in California picked up the 801 concepts in two seminal projects, Stanford MIPS and Berkeley RISC. These were commercialized in the 1980s as the MIPS and SPARC systems. IBM eventually produced RISC designs based on further work on the 801 concept, the IBM POWER architecture, PowerPC, and Power ISA. As the projects matured, many similar designs, produced in the late 1980s and early 1990s, created the central processing units that increased the commercial utility of the Unix workstation and of embedded processors in the laser printer, the router, and similar products. The varieties of RISC processor design include the ARC processor, the DEC Alpha, the AMD Am29000, the ARM architecture, the Atmel AVR, Blackfin, Intel i860, Intel i960, LoongArch, Motorola 88000, the MIPS architecture, the PA-RISC, the Power ISA, the RISC-V, the SuperH, and the SPARC. RISC processors are used in supercomputers, such as the Fugaku.

reduced instruction set computing
Reduced Instruction Set Computing (RISC) is a type of microprocessor architecture that utilizes a small, highly-optimized set of instructions, rather than a more versatile set of instructions often found in other types of architectures. This simplicity allows for more efficient processing and higher performance, mainly due to a uniform instruction size and better use of data pipeline. Each instruction is designed to be executed within one clock cycle, which speeds up the overall execution time.

Reduced instruction set computing
Reduced instruction set computing, or RISC, is a CPU design strategy based on the insight that simplified instructions can provide higher performance if this simplicity enables much faster execution of each instruction. A computer based on this strategy is a reduced instruction set computer, also called RISC. The opposing architecture is known as complex instruction set computing, i.e. CISC. Various suggestions have been made regarding a precise definition of RISC, but the general concept is that of a system that uses a small, highly-optimized set of instructions, rather than a more specialized set of instructions often found in other types of architectures. Another common trait is that RISC systems use the load/store architecture, where memory is normally accessed only through specific instructions, rather than accessed as part of other instructions like add. Although a number of systems from the 1960s and 70s have been identified as being forerunners of RISC, the modern version of the design dates to the 1980s. In particular, two projects at Stanford University and University of California, Berkeley are most associated with the popularization of the concept. Stanford's design would go on to be commercialized as the successful MIPS architecture, while Berkeley's RISC gave its name to the entire concept, commercialized as the SPARC. Another success from this era were IBM's efforts that eventually lead to the Power Architecture. As these projects matured, a wide variety of similar designs flourished in the late 1980s and especially the early 1990s, representing a major force in the Unix workstation market as well as embedded processors in laser printers, routers and similar products.
