Low-power signal chain solutions
based on C5505 DSP for portable
medical application development
Electrocardiogram (ECG), Pulse Oximeter (PO) and
Digital Stethoscope (DS) Medical Development Kits
The portable medical applications market is
growing rapidly and companies with limited
teams and expertise need to enter quickly to
meet consumers’ growing need for devices
that are more portable, consume less power
and provide more sophistication, all at a lower
cost. To answer these needs, TI has launched a
set of medical application development tools
with complete signal chain designs and
software for electrocardiograms, digital
stethoscopes, and pulse oximeter products.
Each of the three medical development kits
(MDKs) is comprised by purchasing an analog
front-end (AFE) module with specific circuitry
design optimized for each end product plus
a TMS320VC5505 DSP Evaluation Module
(EVM). With hardware and software design
information, including schematics, application
source code, medical-specific algorithms and
technical documents, each MDK decreases
the development time for customers by six to
eight months. In addition, MDKs provide a great
evaluation platform to help medical device
manufacturers focus on product differentiation,
like algorithm development and feature
enhancement. They also lower the barrier
for novice developers who want to enter the
medical industry quickly.

To the left is a system block diagram of
the three medical development kits. Through
standard connector interfaces, users can
get the most flexibility of mix-and-match
analog front-end modules with multiple TI
processor platforms, maximizing their return on
investment. Moreover, by choosing low-power
IC components, MDK designs offer longer
battery life to enable more portability in the
end products.
