Computers as Components, 3rd Edition

7.1 Introduction

In this chapter we consider the techniques required to create complex embedded systems. Thus far, our design examples have been small so that important concepts can be conveyed relatively simply. However, most real embedded system designs are inherently complex, given that their functional specifications are rich and they must obey multiple other requirements on cost, performance, and so on. We need methodologies to help guide our design decisions when designing large systems.

In the next section we look at design methodologies in more detail. Section 7.3 studies requirements analysis, which captures informal descriptions of what a system must do, while Section 7.4 considers techniques for more formally specifying system functionality. ...
