Document Summary

High - level language: provides for productivity. & portability: level of abstraction closer to problem domain . Assembly language : textual representations of instructions. Hardware representation: binary digits ( bits, encoded instructions & data. Instruction set is the full supply of instructions of a computer architecture. I or instruction set architecture ( is a) . Communication between hardware & software (cid:8869) related to programming. Operation code cop code ) (cid:8869) provides commands to processor totellitwhatitneedstodo. Large # of instruction sets: complex instruction set computing (cisc) (cid:8869) emphasis on hardware, a . X 86 ( based on intel 8086 cpu: reduced instruction set computing (risc) Less instruction sets (cid:8869) emphasis on software: 9 . D allow anyone to design , manufacture , & sell. A * b: cisc instruction set : Execution times i: cii : multiple # of cycles / instruction. Size is larger j: ric -1 cycle / instruction.
