Reduced Instruction Set Computer (RISC) is a high speed computer processing technology using a simple set of operating commands that allow it to process each command faster.
The idea behind the RISC was that reducing the ISA to a smaller number of more frequently used instructions would produce a more efficient computer. Among the benefits of this design philosophy are simpler instructions that can therefore be more rapidly executed and which result in more efficient compiler-generated code, along with cheaper and easier manufacturing of the chip.Originating as far back as 1974, the RISC concept has been successfully implemented in a number of microprocessers, including those used in IBM's PowerPCs and Sun Microsystem's SPARC workstations.
