A large number of computer programs are discussed in the scientific literature for the implementation of most digital signal processing algorithms. The reader interested in evaluating this type of algorithm is often discouraged by the time and effort he has to spend interfacing the algorithm to his particular processing environment. This paper presents a software testbed package called the Digital Signal Processing Interactive System (DSPIS) which was designed to be a unified and consistent environment for the evaluation of digital signal processing algorithms. Input and output data are confined to seven vectors: X, Y and V for time domain, A, B and W for spectral domain and, finally, C for coefficient domain. Data can be synthesized or transferred from a file into one of the vectors, processed by one or more algorithms and the results (in one or many vectors) can be stored in files. Any vector can be printed out or displayed against its scaled index (except the vector C). DSPIS is menu oriented and permits interactive execution of commands.
