- Moore’s Law – Integrated Circuits resources double every 18-24 months
- Prediction in 1965 by Gordon Moore, Founder of Intel
- Design with future of technology in mind vs present of technology
- Represented by the graph below
‘up and to the right’ graph
- Abstraction – Represent the design at different levels of representation
- Increases productivity and decreases design time
- Lower levels details are hidden to make it simple = higher level details
abstract painting
- Common Case Efficiency – Enhance efficiency more than the efficiency of rare cases
- Experimentation and measurement is required
- Fast sport cars versus fast minivan?
Jaguar F-Type
- Parallelism Efficiency – Performing operations in parallel
- Increases performance
- Represented by the jet engines on a plane below
Dual engines on jet
- Pipelining Efficiency – Pattern of parallelism
- Has a particular sequence with different stages
- Represented by ventilation in data centers
Air ventilation of data centers
- Prediction Efficiency – Easier to ask for forgiveness than permission
- As long as prediction is not expensive and is accurate
- Represented by the sky for weather forecasting
Weather forecasting based on clouds
- Memory Structure – Required to be fast, large, and cheap
- Memory speeds hinders performance while capacity limits unsolvable issues
- Memory is one of the most expensive component in computers
- Cache versus Random Access Memory (RAM) versus Hard Disk Drive (HDD)
- Represented by a pyramid with cache at the top and HDD at the bottom
Pyramid memory structure
- Redundancy Dependency – Components for detecting and resolving failures
- Moral of the story is that any device can fail
- Represented by emergency procedures when flying a plane
Emergency procedure for crashed plane
