A RISC instruction set is characterised by

  • A.few, simple, fixed-length instructions executing in one cycle
  • B.many complex instructions, each doing as much work as possible
  • C.instructions that may access memory at several points in their execution
  • D.variable-length instructions decoded by microcode within the processor

Answer: A

Regularity is the point: a fixed format is easy to decode and easy to pipeline, and the compiler is left to build complex operations from simple ones. Only load and store touch memory, which keeps the pipeline predictable.
