A PARTITIONING TECHNIQUE FOR CONCURRENT SOFTWARE-DESIGN

Software partitioning is the process of mapping software functional re quirements into a set of program modules for implementation. This pape r analyzes concurrent software design techniques that are based on str uctured analysis and design (SA/SD) in order to highlight their potent ial and their shortcomings. A partitioning technique based on the anal ysis of the data and control flow of a system's functional requirement s is proposed next. This technique, called the Concurrent Software Des ign Technique (CSDT), extends the current SA/SD techniques by identify ing concurrent independent tasks for implementation in multitasking or multiprocessing environments. Finally, the application of this techni que is illustrated through an example.
