The NI-DSP Software Reference Manual for LabVIEW for Windows explains how to use the NI-DSP software
package for the LabVIEW for Windows environment.  The NI-DSP software package contains the NI-DSP Analysis
VIs, which are high-level digital signal processing (DSP) VIs that call the functions that execute on the
AT-DSP2200 plug-in board for IBM AT bus and compatible computers.  This manual describes how to use the
NI-DSP Analysis VIs to develop applications in LabVIEW using the AT-DSP2200 board.

The NI-DSP software package also contains the NI-DSP Interface Utilities.  The NI-DSP Interface Utilities are a set
of tools and examples that help you customize your NI-DSP Analysis VIs and the DSP Library, which is resident on
the board.  This manual contains step-by-step instructions and useful examples to help the LabVIEW developer add
custom algorithms to the NI-DSP Analysis VIs using the NI-DSP Interface Utilities.

The material in this manual is for users who are familiar with LabVIEW and the IBM family of computers and
compatible computers.

This manual is divided into four parts.

•

Part 1, Getting Started with NI-DSP, contains a brief product overview, information about the NI-DSP for
LabVIEW for Windows package, and the procedure for installing the software.

•

Part 2, Introduction to the NI-DSP Analysis VIs, describes how to use the NI-DSP Analysis VIs in your
LabVIEW applications.  This part also describes how to manage memory on the DSP board from your
LabVIEW application, and how to transfer data between your LabVIEW application and the NI-DSP functions
on the board.  This part contains general guidelines for developing NI-DSP applications within LabVIEW.

•

Part 3, NI-DSP Function Reference, is intended as a reference for users familiar with Part 2.  Part 3 is organized
as follows:

-

Chapter 1, NI-DSP Analysis VI Reference Overview, contains an overview of the NI-DSP Analysis VIs and
includes a list of the VIs.  This chapter describes how the NI-DSP Analysis VIs are organized, and how to
access them.

-

Chapter 2, NI-DSP Analysis VI Reference, contains a brief explanation of each NI-DSP Analysis VI.  The
VIs are arranged alphabetically.

•

Part 4, NI-DSP Interface Utilities, explains how to customize the NI-DSP Analysis Library on the board and to
create and run interfaces in LabVIEW to your custom library functions.  Part 4 is organized as follows:

-

Chapter 1, Introduction to the NI-DSP Interface Utilities, contains an overview of the NI-DSP Interface
Utilities, installation instructions, and explains how to use the NI-DSP Interface Utilities.

-

Chapter 2, Getting Started with the NI-DSP Interface Utilities, contains a step-by-step example for building
a custom DSP Library, creating a LabVIEW interface to a custom function, and executing the custom
function from the LabVIEW environment.  The chapter demonstrates this concept with an example of how
to add a custom function.
