system architecture

system architecture

1. PAMM

   • MAR
     • memory address register
   • MDR
     • memory data register
     • data fetched memory
   • PC
     • program counter
   • ACC
     • accumulator
     • stores results ALU

2. CPU

   • central processing unit
   • improve speed
     • increase cores
     • increase cache
     • increase clockspeed
   • fetch, decode, execute

3. cache

   • in the cpu
   • quick to access
   • frequently used instructions
   • 3 stages

4. control unit

   • controls data flow
   • in the cpu

5. clockspeed

   • herts
   • FDE cycles/second

6. cores

   • cycles done simultaneously

7. ALU

   • logical decisions, calculationss

8. registers

   • high speed memory

9. von-neuman architecture

   • (data, instructions) stored
