CPU Architecture

1. Purpose of CPU

   • Fetch
   • Decode
   • Execute

2. CPU Components

   • Cache
     • High-speed memory
   • Control unit
     • Controls information flow
   • Arithmetic logic unit
     • Calculation and logic

3. Registers

   • Memory Address Register
     • Stores current address
