4 – Software Design

Publisher Summary This presents some basic software concepts, focusing on the embedded environment. There are a number of ways to document software for an embedded system. The methods include data flow diagram, state diagram, flowcharts, and pseudocode. The software specifications tend to be the one document that is never produced or is produced at the end of the project and in a hurry. The level of documentation required depends on the customer and the complexity of the system. Embedded systems are self-contained, with memory and other resource limitations. Software for embedded systems must work within these constraints, and that is what sets it apart from the software in a PC.
