“The Brain”…
I will rule the world!

2. Intro
CPU
Parts
Cores
Speed
GPU
Why?

3. CPU
Parts

4. Core(s)

5. Core(s) Control Unit Load from RAM to register
Store from register to secondary storage
Send math to A/L U
Choose route “branch”

6. Core(s) A/L U Perform math functions Logical operations compare
True/false

7. Core(s)
Registers
CPU memory for active instructions
Very small amount

8. Core(s) Multicore Just what is says more than one
Separate operations at the same time
Share connection memory and bandwith
History
Single – Intel
Dual – Oct 2005
Quad – Jun 06
Hex – Sep 08
8 Core (Intel/AMD) & 12 core (AMD) – Mar 2010
16 Core (AMD) – Nov 2011

9. Speed Clock rate Bus rate Speed drawback Processing speed
Operations per cycle
Bus rate
16-bit
32-bit
64-bit
Speed drawback
HEAT!!!

10. GPU Why Simple operations, but lots of them Parallel programming
Use all the power available
8 core = 128 parallel paths

11. GPU
CUDA
Programming that takes advantage of both CPU & GPU processing power
Splits instructions into pieces
CPU – instruction
GPU – graphics
Separate memory available for each

12. CPU/GPU Processing CPU GPU 64 operations looped processing Serial
128 nanoseconds to complete
GPU
Parallel
10 nanoseconds to complete
