computing

1. cores

   • dual core
     • quad core
       • 8 core
         • each core executes instructions independently
           • dual core may execute up to twice as many instructions per second

2. cache

   • the cache acts as an intermediary between the processor and the main memory
   • as programs are executing, the cache holds commonly used instructions

3. what affects performance?

   • clock speed
     • cache size
       • cores

4. embedded systems

   • a computer system that is made up of both hardware and software
