Systems Architecture

1. CPU

   • Performance
     • clock speed
       • FDE per second
     • Cores
       • multiple processes
     • cache
       • frequently used instructions
       • very small size
       • much faster
   • FDE cycle instructions
   • Registers
     • ACC
       • stores ALU results
     • PC
       • program counter
     • MAR
       • memory address register
     • MDR
       • memory data register
   • Von Neumann Architecture
     • data together memory
   • ALU
     • arithmetic logic unit
