DADiSP® Product Background
DADiSP (Data Analysis and Display), developed by DSP Development Corporation
of Newton, MA, is the first
general purpose personal productivity software for
scientists and engineers. Through a sophisticated
integration of powerful computational and analytical
capabilities, DADiSP allows users to depict and
manipulate large amounts of data in an interactive,
DADiSP has long been considered the standard for data
analysis in laboratory automation, data reduction, speech
processing, sonar and radar applications, digital signal
processing, computer-aided engineering, and other fields.
It delivers the power, flexibility, extendibility and
ease-of-use that make it applicable to a wide range of
technical computing tasks.
The Worksheet Model
DADiSP is a general purpose analytical tool for
scientists and engineers much like the spreadsheet is a
tool for financial analysts. However, DADiSP replaces the
rows-and-columns ledger format with a graphical interface
that meets the technical user's needs for interactive
visual analysis of large amounts of data. A DADiSP
Worksheet consists of a series of windows in which data is displayed
and manipulated in a variety of graphical and tabular
styles simultaneously, according to the user's requirements and
applications. DADiSP users can perform multiple complex
operations in one window and view results in other
Dozens of windows may be created and viewed on the screen
at once, with the ability to zoom in or out of graphs, to
scroll, and to overlay graphs as needed. In addition,
changes made to a singe window automatically cause
dependent windows to recalculate and update. In all
cases, the user interacts with the data visually, through
the keyboard, a mouse, through user-defined SPL (Series
Processing Language) routines and DADiSP command scripts
or through existing, application-specific external
programs that work seamlessly with DADiSP.
The multiple windows allow DADiSP to perform a variety of
tasks such as data reduction, pattern recognition, peak
analysis, statistical analysis, mathematical analysis,
Fourier transforms, convolutions, digital filtering,
waterfall plots, three-dimensional plots, and many other
operations. There are over 2000 functions available for
Aside from its power and flexibility, one of the main
features of DADiSP is its graphical user interface which
speeds analysis for the novice user and the experienced
"power user" alike. Using a variety of icons, menus,
property sheets and dialog boxes, DADiSP guides the user
through the needed computational and analytical tools.
Also important to users and managers making buying
decisions, DADiSP presents a consistent interface across
all computing platforms. This
simplifies and minimizes training and ensures users that
skills learned in one version of DADiSP are readily
applicable to any other.
Flexible Data Sources
DADiSP allows users to enter data manually or bring in
data sets from a variety of sources including ASCII, CSV,
8-bit byte, 16-bit integer, 32-bit integer, 64-bit integer, IEEE
single and double precision floating point files, industry and vendor
specific formats or
directly from many common data measurement or acquisition
With command file, user-definable macro capability, and
SPL, DADiSP also provides the flexibility and
extendibility needed to customize the software and
automate DADiSP sessions for specific applications
DADiSP supports Windows 64-bit and Windows 32-bit operating
systems in use at many technical organizations. Classic versions of DADiSP also
run under X-Windows Motif on legacy workstations from Sun
Microsystems, Hewlett-Packard, IBM, Concurrent, Digital
Equipment Corporation, NeXT, and Silicon Graphics.
DSP continually upgrades DADiSP in response to the
increased accessibility and demand for powerful and
very low-cost PC's and the growing need
among technical users for a truly general purpose
productivity software package.
Over 25 Years of Experience
Based on more then 25 years of experience serving the
technical market, DSP continues to extend existing DADiSP features
and add new ones to address an expanding market.
Key new features of DADiSP are:
- Enhanced and streamlined user interface
- Standalone, external Worksheet files (.dwk)
- Active Document Support for embedding into Word,
- Just in Time memory management for faster
- Virtual series processing for seamless manipulation of big datasets

In addition to these new features, DADiSP offers the
ability to capture data from numerous sources,
multiple data views, a wide array of mathematical and
graphical analysis functions, extensive signal
processing features, ActiveX and the DSP Pipeline to
run external programs from within DADiSP, textual and
graphic annotation of windows, virtually no limits on data
size, high speed 64-bit IEEE standard double precision
arithmetic, and publication quality hardcopy.
Technical Productivity Tool
Just as Excel serves as a
general purpose application for business and financial
users, DADiSP offers a robust set of features to serve as
a rich and diverse productivity tool for scientists and engineers.
The Market Need
Before DADiSP, there was no single general purpose
productivity package for the technical user.
Traditional financial spreadsheets were powerful and
effective for manipulating numerical data, but
required extensive customization to meet users'
needs. Designed for general business use,
spreadsheets were cumbersome for visual analysis of
large data sets.
Technical software applications have been available
for PC's, but most packages are designed to
perform a very specific task. Like spreadsheets,
these packages require extensive customization.
General Purpose Solution
DADiSP fulfills the need for a general purpose
software package that is designed specifically for
the technical user. Although it can be customized, it
does not require customization to get the job
Another important factor driving this need is the
rapid growth of the technical PC market. Prices have
fallen while computing power has jumped, making it
feasible for many organizations to place high performance
PC's on every engineer's desk. General purpose software is needed
to allow companies and individuals to reap the full
benefit of the competitive advantages provided by this
DADiSP's market-tested power and flexibility make it
an ideal software tool for the high performance
PC user in a technical organization.
