2.1 Hardware System Structure

Traditionally, embedded systems have made a simple distinction between subsystems primarily used for processing application data and subsystems used for housekeeping functions. A simple view of this structure is shown in Fig 2-1. This partitioning into control and data flows works well when the data processing is simple (but very demanding in bandwidth ...
