What Are The Characteristics Of Risc Isa?

Answer»

RISC ISA Characteristics 

  • All operations on data apply to data in registers and typically change the ENTIRE register; ‰
  • The only operations that affect memory are load and store operations that move data from memory to a register or to memory from a register, RESPECTIVELY; 
  • ‰A small NUMBER of memory addressing modes;
  • The instruction formats are few in number with all instructions typically being one size;
  • Large number of registers; ‰

These simple properties LEAD to DRAMATIC simplifications in the implementation of advanced pipelining techniques, which is why RISC architecture instruction sets were designed this way.
