 for RISC
From WordNet (r) 3.0 (2006) :

      n 1: (computer science) a kind of computer architecture that has
           a relatively small set of computer instructions that it can
           perform [syn: reduced instruction set computing, reduced
           instruction set computer, RISC] [ant: CISC, complex
           instruction set computer, complex instruction set

         Reduced Instruction Set Code (CPU)

From The Free On-line Dictionary of Computing (30 December 2018) :

  Reduced Instruction Set Computer
      (RISC) A processor whose design is based on the
     rapid execution of a sequence of simple instructions rather
     than on the provision of a large variety of complex
     instructions (as in a Complex Instruction Set Computer).
     Features which are generally found in RISC designs are uniform
     instruction encoding (e.g. the op-code is always in the same
     bit positions in each instruction which is always one word
     long), which allows faster decoding; a homogenous register
     set, allowing any register to be used in any context and
     simplifying compiler design; and simple addressing modes
     with more complex modes replaced by sequences of simple
     arithmetic instructions.
     Examples of (more or less) RISC processors are the Berkeley
     RISC, HP-PA, Clipper, i960, AMD 29000, MIPS R2000
     and DEC Alpha.  IBM's first RISC computer was the RT/PC
     ({IBM 801), they now produce the RISC-based RISC
     System/6000 and SP/2 lines.
     Despite Apple Computer's bogus claims for their
     PowerPC-based Macintoshes, the first RISC processor used
     in a personal computer was the Advanced RISC Machine (ARM)
     used in the Acorn Archimedes.
