A dynamic scaling (DS) method is proposed as a cost-effective means of eliminating overflow and limit cycle oscillations in fixed-point direct-form recursive filters. It is implemented by adding a DS unit to a fixed-point on-line module without modifying latter. On-line modules consume inputs and produce outputs digit serially, most significant digit first.(More)
In software development there exists a tension between quality, cost, and time. Delivering cost competitive quality software in Sri Lanka today‘s time constrained market is a difficult task. Users and producers of software must contend with issues concerning features, those to include and those to exclude. Many traditional software processes are heavy with(More)
Autumn 1997 29 Introduction The microprocessor, which evolved from the inventions of the transistor and the integrated circuit (IC), is today an icon of the information age. The pervasiveness of the microprocessor in this age goes far beyond the wildest imagination at the time of the first microprocessor. From the fastest computers to the simplest toys, the(More)
