What is presented here as a software design process is a generalized form that will have to be tailored to conform to the various life cycles involved. 15.2.1 Design Process. The software design phase falls between requirements definition and integration. As shown in Figure 15-1, the in- puts to the software design process are the software requirements. The software developed during the design phase is passed on to the integration and test phase.

Our motive for doing this might be to explore what seems to be a difficult part of the software. We might thereby hope to gain insights that guide us in refining the rest of the structure.. This idea of trying to ignore the detail of lower levels of the design is easier said than done and takes some nerve. It is a real test of whether we believe software design is worthwhile and whether we can resist the temptation to rush on to coding pieces of the software..

The use of programming models for the software design of heteroge- neous MPSoC requires the definition of new design automation methods to enable concurrent design of hardware and software. models to deal with nonstandard application specific hardware–software interfaces at several abstraction levels.. In this chapter, we give the definition of the programming models to abstract hardware–software interfaces in the case of heterogeneous MPSoC..

In order to increase the design productivity of embedded software, we propose a novel methodology for embedded software design based on a. parallel programming model, called a common intermediate code (CIC). In a CIC, the functional and data parallelism of application tasks are specified independent of the target architecture and design constraints.

Indeed, whereas design and implementation are considered largely distinct activities in tradition- al software development, using the object-oriented paradigm the two activities are often indistinguishable. Prototyping is seen as an integral part of the object-oriented software design and imple- mentation process.

However, a formal and detailed description of the customer requirements is needed before the project commences. requirements of the client, software design, and standards. This is because an untimely change adversely, impacts the cost of the software project. The software project manager must decide with the customer upon a set of objectives that must be achieved at the end of the project..

Relational database design has evolved from an art to a science that has been made partially implementable as a set of software design aids.. Many of these design aids have appeared as the database component of computer-aided software engineering (CASE) tools, and many of them offer interactive modeling capability using a simplified data modeling approach.

The HdS is made of the lower software layers that may incorporate an operating sys- tem (OS), communication management, and a hardware abstraction layer (HAL) to allow the OS functions to access the hardware resources of the platform. Traditional software development strategies make use of the concept of a software development platform to debug the software before the hardware is ready, thus allowing parallel hardware–software design.

Data flow design is a method for carrying out the architectural (large-scale) design of software. Data flow design depends on identifying the flows of data through the intend- ed software, together with the transformations on the flows of data. The method leads from a specification of the software to a large-scale structure for the software expressed in terms of:. the constituent components of the software.

Arguably data flow design leads to the most modular structure for the software, since the design is based on “data coupling” (the best type) between the components.. 120 Chapter 9 ■ Data flow design. 9.7 Suggest features for a software toolkit to assist in using data flow design.. Data flow design is described in: E. The method is variously called the Michael Jackson program design method (after the name of its inventor), or Jackson Structured Programming (JSP), and data structure design..
