摘要: In this paper, the problem of finding good wordlength combinations for fixed-point digital signal processing flowgraphs is addressed. By formulating and solving an approximate optimization problem, estimated Pareto-optimal curve attainable cost/quality rapidly calculated. This associated are useful in several situations can serve as starting points real design searches. Examples that illustrate these concepts given.
