DSPs Enable Innovation for Rice Team
The ability to perform extremely sensitive gas detections with smaller,
cheaper instruments opened up a wide range of new applications for the Rice
research team. The Rice
University team used TI's Code Composer Studio(TM) software to program the
F2812 controller, which made it possible to move through all phases of the
development process within a single integrated development environment (IDE).

TI Enables Innovation with Broad Range of Controllers
From ultra low power MSP430 and 32-bit general purpose TMS470 ARM7-based
MCUs to high performance TMS320C2000(TM) digital signal controllers, TI offers
designers the broadest range of embedded control solutions.ti.

Another potential application under investigation is the use of the new
generation of instruments to provide early warning of chemical or biological
attack ."
After receiving data from the detector, the F2812 controller uses the on-
chip analog-to -digital converter (ADC) to convert the detector signal and
digitally averages a large number of samples in order to increase the signal-
to-noise ratio.

"We believe the introduction of the 755MM product line
will provide system designers a more competitive alternative to existing
technology available today," Dr. Frank Tittel, the J.
"TI's F2812 controller not only gave us DSP-enabled real-time processing
for increased sensitivity and more precise readings, but it also performed the
functions of the PC and digital-to-analog converters (DAC), allowing us to
replace these devices with a single chip," said Dr. "By lowering our
component count, we reduced the laser sensor's size and weight, and the cost
of the associated electronics fell from thousands of dollars in the previous
generation to the price of one C2000(TM) digital signal controller. Then, the system processes the data and performs corrections
before performing linear fits with data from a known sample of the target gas
to determine the concentration.ti.
