System Architecture

System Architecture

1. Von Neumann architecture

   • Can you describe the Von Neumann architecture?
   • What are the Von Neumann architecture components?
     • Control Unit
     • Arithemetic/Logic unit
     • Memory Unit
     • CPU

2. System Architecture Components

   • Registers
     • Memory Location within the CPU itself
     • Program counter
     • Current instruction register
     • Accumulator
   • Buses
     • Bundle of cables
     • Used when data needs to be transmitted between components
   • Clock
     • Contained in the control Unit
     • Measured in Hertz (Hz)
     • Vibration controlled by quartz crystal

3. Performance

   • Increasing Performance
     • Faster CPU, More CPU
     • Faster Memory- more cache and higher speed memory
   • Speed up processing
   • Speed up memory
   • Virtual Memory
