D 8 . 4 QuickSig - AN OB JECT - ORIENTED SIGNAL PROCESSING ENVIRONMENT
نویسندگان
چکیده
A new object-oriented DSP environment called QuickSig is described. It is based on the latest developments in object-oriented programming (New Flavors on Symbolics Lisp machines). The design philosophy of QuickSig has been to extend the Lisp language by a layer of general DSP constructs; abstract data structures like signals, filters, windows, graphical presentations and related signal processing operations. QuickSig is targeted to be a fast prototyping system for algorithmic development. It is easily extendable to include new ways of modeling signals and signal processing, both numerical and symbolic. This paper describes the main features of the present system and some new features that are under development.
