Advance computer architecture

  1. 1. NADAR SARASWATHI COLLEGE OF ARTS AND SCIENCE DEPARTMENT OF INFORMATION TECHNOLOGY NAME : P.RITHIKA TOPIC : PROCESSOR AND MEMORY HIERARCHY CLASS : I-M.SC(IT)
  2. 2. PROCESSORS : • • •
  3. 3. WHAT IS MEANT BY MEMORY HIERARCHY ? • • • • •
  4. 4. MEMORY HIERARCHY IN COMPUTER ARCHITECTURE ? • •
  5. 5. PRIMARY MEMORY : •
  6. 6. SECONDARY MEMORY : •
  7. 7. CHARACTER OF MEMORY HIERARCHY : PERFORMANCE: PREVIOUSLY, THE DESIGNING OF A COMPUTER SYSTEM WAS DONE WITHOUT MEMORY HIERARCHY, AND THE SPEED GAP AMONG THE MAIN MEMORY AS WELL AS THE CPU REGISTERS ENHANCES BECAUSE OF THE HUGE DISPARITY IN ACCESS TIME, WHICH WILL CAUSE THE LOWER PERFORMANCE OF THE SYSTEM. SO, THE ENHANCEMENT WAS MANDATORY. THE ENHANCEMENT OF THIS WAS DESIGNED IN THE MEMORY HIERARCHY MODEL DUE TO THE SYSTEM’S PERFORMANCE INCREASE.
  8. 8. ABILITY : • THE ABILITY OF THE MEMORY HIERARCHY IS THE TOTAL AMOUNT OF DATA THE MEMORY CAN STORE. BECAUSE WHENEVER WE SHIFT FROM TOP TO BOTTOM INSIDE THE MEMORY HIERARCHY, THEN THE CAPACITY WILL INCREASE.
  9. 9. MEMORY HIERARCHY DESIGN : • 1.REGISTER • 2.CACHE MEMORY • 3.MAIN MEMORY • 4.MAGNETIC DISKS • 5.MAGENTIC TAPE
