RISC CONCEPTS WITH ARM
cisc evolution
 THE ART OF PROCESSOR DESIGN IS TO DEFINE AN INSTRN SET THAT SUPPORTS FUNCTIONS
 WHAT SORT INSTRN SET MAKES A GOOD COMPILER TARGET
WHY DOES COMPILER NEEDED???
 THE SEMANTIC GAP BETWEEN A HIGH LEVEL LANGUAGE CONSTRUCT AND A MACHINE INSTRN IS BRIDGED BY COMPILER
COMPILER TARGET ??
 THE AIM OF PROCESSOR DESIGN SHOULD DEFINE HIS OR HER INSRTN SET TO BE GOOD COMPILER TARGET
 THIS LEDS TO THE CISC DEVELOPMEENT
 MINI COMPUTERS DEVELOPED WHICH HAS MAIN MEMORY CONTROLLED BY MICRO CODE ROMS WHICH ARE FASTER THAN MAIN MEMORY
 MINI COMPUTERS USES CISC
 IN 1970, MICRO PROCESSORS DEVEL0PED FASTLY IN SEMICONDUCTOR INDUSTRY BUT MICRO CODE ROM IS NEEDED FOR ALL COMPLEX ROUTINES
 CISC IS NOTHING BUT MP WITH MINICOMPUTER INSTRN SET
WHAT IS CISC ??
 CISC is an acronym for Complex Instruction Set Computer and are chips that are easy to program and which make efficient use of memory. Since the earliest machines were programmed in assembly language and memory was slow and expensive,
WHAT IS RISC ??
 RISC, or Reduced Instruction Set Computer. is a type of microprocessor architecture that utilizes a small, highly-optimized set of instructions, rather than a more specialized set of instructions often found in other types of architectures.
