Upgrade of LabVIEW for Windows Controls Digital Signal Processing Hardware
and RTSI Bus

March 24, 1993 -- Austin, TX - National Instruments today announced a new
version of its popular LabVIEW instrumentation software for Windows.
LabVIEW Version 2.5.2 includes new virtual instruments (VIs) for use with
the company's AT-DSP2200 hardware, new DSP stand-alone development
capabilities, and a new DSP Custom Function VI for accessing user-designed
DSP board functions. Version 2.5.2 also has added functionality for
data-acquisition-board-to-DSP board serial data communication using the
Real-Time System Integration (RTSI) bus.

The new NI-DSP Analysis VI Library for LabVIEW for Windows contains VIs for
signal generation, frequency-domain operations, time-domain operations,
windowing, array manipulation, filtering, and memory management on the
AT-DSP2200. The library combines the innovative graphical programming
methodology of LabVIEW with the performance of the DSP board. Users can
access data on the DSP board by a "memory handle" that corresponds to a
DSP board memory location. Using memory handles to access data directly in
DSP memory offers maximum performance because you can acquire data with
onboard A/D converters directly to DSP memory, and operate the data "in
place" without ever transferring the data to the AT bus.

The package also contains new C development tools for DSP stand-alone
development. The tools include DSP board-level data acquisition C function
calls for accessing the onboard A/D and D/A converters from a stand-alone
DSP application developed with the AT&T WE DSP32C Developers Toolkit. In
addition, the LabVIEW DSP Custom Function VI accesses user-defined
functions in NI-DSP or stand-alone DSP applications written in C with the
AT&T WE DSP32C Developers Toolkit.

LabVIEW users can also now collect data into DSP memory from the company's
other data acquisition boards, such as the AT-MIO-16X, over the RTSI bus
serial link, without transferring data to the host PC memory. The RTSI bus
uses a custom gate array and ribbon cable to route triggering signals for
synchronizing multiple plug-in boards and to route serial data between
data acquisition boards and the AT-DSP2200.

These new DSP software tools help two types of users - those who want to
develop a LabVIEW-supervised application to gain increased performance by
programming the DSP board with memory handles, and those who want maximum
speedup by developing a stand-alone or DSP supervised application using
board-level data acquisition calls, RTSI, and the LabVIEW DSP Custom
Function VI.

Pricing, Availability, and for More Information 

LabVIEW Version 2.5.2 for Windows is available now for $1,995. LabVIEW
Version 2.5 users can upgrade at no charge. NI-DSP Analysis VI Library for
LabVIEW for Windows is packaged with the AT-DSP2200 hardware and is only
compatible with LabVIEW for Windows 2.5.2. The AT-DSP2200 series boards
are available now, with pricing from $2,495 to $4,495, depending on memory
configuration.
