LabVIEW®DSP Interface
DirectDSP®software
allows the widely used LabVIEW data acq. and
instrument software to access non-National Instruments DSP/data acquisition boards.
DirectDSP?provides VIs (virtual instruments) which augment LabVIEW with direct access
to more than 80 types of DSP and data acquisition hardware,
including DSP and math functions and real-time DSP processing.
Directly from LabVIEW VIs,
DirectDSP® software provides DSP
and data acquisition functions, including "hot-line" access to the DSP, onchip
and onboard memory, serial and other digital I/O, and analog I/O channels. DirectDSP?provides four (4) levels of VIs: demos, high-level functions, instrument functions, and
low-level (library) functions. Over 100 low-level library functions are provided,
including board and DSP control, board configuration and interrogation, analog I/O
sampling rate calculation and other setup, onchip and onboard memory transfer, DSP program
(COFF) file download, and DSP data type conversion. When combined with the company's
Hypersignal software, higher-level VI functions are active, including
continuous streaming to/from hard disk, arbitrary waveform generation, stimulus &
response measurement, and instrumentation functions such as spectrum analyzer and digital
oscilloscope.
DirectDSP® software supports LabVIEW v6.1, and
includes several VI diagram and instrument panel examples. Demo VIs are included which
display a list of available hardware drivers on start-up.
The
company's supported hardware list offers a wide range of DSP/data acquisition hardware
manufactures, including Innovative Integration, Sanmina-InterWorks, Texas Instruments, Motorola,
and more. Several types of data acquisition hardware types are available, with sampling rates
ranging from dc to 40 MHz.
Hardware types include multichannel,
industrial automation and control, sonar and acoustic/audio, instrumentation grade, and
very low-cost. In addition to numerous analog I/O options, other typical board options
include serial and parallel digital I/O, amount of SRAM, and DSP clock speed.
