Techniques for developing and testing microprocessor systems

Testing microprocessor systems at the development stage can take up to a third of the total development time and yet techniques for testing may only be thought about once the design stage has been undertaken. A correct approach to testing can considerably reduce the time needed to take a prototype through to a working system, and this not only means that a product can be on the market faster, but the development costs can be considerably reduced. The paper looks at the techniques and requirements for testing microprocessor-based systems and suggests alternatives to expensive development systems.
