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.
