This application report presents a modem reference design based on the TMS320LC56 DSP. The advanced peripherals of this device provide the features necessary for integration into complex systems optimizing access times and minimizing external logic. A software analysis at the beginning shows that the computing power of the LC56 is sufficient to support even the highest standards of voice and data

The DSP/BIOS™ Link software has been designed to implement inter-processor communication between a host device and a DSP. For the case of OMAP591x devices the default configuration of the DSP/BIOS Link software requires that 2MB of system memory is reserved for exclusive use by DSP/BIOS Link. The intention was to provide developers using DSP/BIOS Link plenty of memory to begin with and enab

This application report describes how to implement an ultra-low-power photo-diode-based smoke detector using the MSP430F2012 and an external operational amplifier that is powered from two AAA batterie

TMS320VC5421 Bootloader Technical Reference

Many boost converters have an external rectifier diode. The input voltage of the TPS6510x and TPS6514x main boost converter is connected to the output voltage when the device is disabled. Due to the d

This application report shows an innovative way to use the DualSync functionality of the CC112x/CC120x to handle a new kind of preamble. By using what is called SmartPreamble the receiver is able to reliably detect exactly where it woke up in the preamble and use the eWOR timer to go back to sleep and then wake up right before the sync word.

This application note provides an overview of the DMA architecture specified by the TMS320 DSP Algorithm Standard (also known as XDAIS). It also describes two sets of APIs used for accessing DMA resources: the IDMA2 abstract interface and the ACPY2 library. In addition to providing an overview of fundamental DMA abstractions for eXpressDSP-compliant algorithms this application note highlight

This application note describes the operation and application of the UC3906 sealed lead-acid battery-charger IC. Several charging circuits using this IC are described along with expected improvements in battery performance. This note also discusses uses for the many auxiliary functions of the part.

This design note describes a typical application circuit for +12VDC input to +5VDC/1A output. A demonstration kit circuit schematic and list of materials are included.

DAC348x PLL Consideration and Tradeoffs when using the DAC348x

This report discusses 32-kbit/s Adaptive Differential Pulse Code Modulation (ADPCM) transcoders. A half-duplex ADPCM transcoder which complies with the CCITT recommendation (G.721) can be achieved with a single TMS32010. If the transcoder is used only for private lines a full duplex non-CCITT ADPCM transcoder is more cost-effective and can be designed with a single TMS32010 processor. Both the

This application report describes the power sequencing requirements for all TCI100 devices with respect to the dependencies associated with reset clock and signal pins during power up. It also explains what to avoid and potential issues associated with power-up sequencing with respect to the external memory interface (EMIF) peripheral.

This application report details the measurement principles for using an LC sensor to detect rotational movement. Based on this measurement principle an example project is presented demonstrating conta
