Von Neumann Architecture

Von Neumann Architecture

1. CPU performance

   • cores
     • more processes simultaneously
   • clock speed
     • FDE cycles /s
   • cache
     • frequently used in structions
     • quick to access

2. ALU

   • arithmetic logic unit
   • results stored in accumulator

3. Control Unit

   • controls data flow

4. registers

   • MAR
     • memory address register
     • instruction being executed's address
   • MDR
     • memory address register
     • fetched data value
   • accumulator
     • stores ALU results
   • program counter
     • next instruction address
