**DADiSP** (Data Analysis and Display, pronounced day-disp) is a computer program developed by *DSP Development Corporation* which allows one to display and manipulate data series, matrices and images in an environment similar to a spreadsheet.

A DADiSP Worksheet consists of multiple interrelated windows such that a change to the data in one window automatically updates all dependent windows. DADiSP includes a series based programming language called SPL (Series Processing Language) used to implement custom algorithms.

DADiSP is widely used in the study of signal processing, numerical analysis and statistical data analysis applications.

DADiSP was originally developed in the early 1980’s as part of a research project at MIT to explore the aerodynamics of Formula One racing cars.
