1 C5535 DSPShield
The C5535 DSPShield is an evaluation board for the Texas Instruments TMS320C5535
Fixed-Point Digital Signal Processor (DSP). It is designed to be both a “Shield” (i.e.
daughter card) for the Arduino Open-Hardware family of microcontroller (uC) boards
and also a stand-alone development board. With a rich set of hardware features and a
connector for prototyping expansion, the C5535 DSPShield can be used to develop
applications such as
•
Wireless Audio Devices (e.g., Headsets, Microphones, Speakerphones)
•
Echo Cancellation Headphones
•
Portable Medical Devices
•
Voice Applications
•
Industrial Controls
•
Fingerprint Biometrics
•
Software-defined Radio
