System Design 1
Most embedded microprocessor designs involve processing some kind of input
to produce some kind of output, and one or both of these is usually analog. The
digital portions of an analog system, such as the microprocessor-to-memory
interface, are outside the scope of this book. However, there are some system
considerations in any design that must interface to the real world, and these will
be considered here.
Dynamic Range
Before a system can be designed, the dynamic range of the inputs and outputs
must be known. The dynamic range defines the precision that must be applied to
measuring the inputs or generating the outputs. This in turn
