Embedded Systems in Cars

The number of embedded systems are in 2003 Volvo and Mercedes are 50, and 100 respectively.

So the key questions are:

1. What is the purpose of so many embedded processors?

2. What do they do?

3. Why should they be different?

Let's use a simple car metaphor to illustrate.

1. First, a car's engine should operate at peak efficiency because gas prices are high.

2. Second, braking must be coordinated with speed, curves, slopes, and traction to avoid skidding.

3. Third, in luxury cars, the temperature should be regulated in response to outside conditions, so we don't have to step into a frozen car on a snowy day.

Typical characteristics desired from embedded processors include

1. Real-time performance and extremely high efficiency.

2. They also need very low energy consumption, or the battery will quickly drain.

3. Lastly, they must be very cost-effective since there are hundreds of thousands of processors, and keeping costs low is essential.
