## Embedded Systems
Usually in the embedded field we have constrained resources with respect to the general purpose world.
For example:
- Very few memory/storage/processing power
- Thermal/power consumption constraints.

It is not so easy to define an __embedded__ architecture, the basic is a Von Neumann model with
emphasis on sensors/actuators and power constraints.

## Embedded Market Status
While we still haven't smart houses?
There is no market, so there is no need.

And also the market is very fragmented because there is no collaboration between brands.

There are some advancements in the *automotive market*
In 2007 there was balance between the cost of the iron and cost of the electronics in the
automotive market, nowadays the electronics cost more.

## Application Contexts
__The four directions are__
- Nomadic
- Public Infrastructures
- Industrial Systems
- Private Spaces
__While two recurring needs are__
- Networking
- Sensing

## Solutions
There is not a unique solution, but there are some good or worse solutions.
For example wifi is not suited for the embedded market, but other technologies like ZigBee and BLE also have limitations.

## Direction
- Networked
- Secure
- Complex:
   - Giga complexity by nano technology
   - Complex through heterogeneity
- Thermal/power control: run-time management of resources.

## Embedded Systems Design
Field knowledge is necessary so and emb. eng. have to cooperate with domain experts or keep in mind
notion of physics.
