This application report provides a complete working example of a C-language program to initialize the TVP5020 NTSC/PAL video decoder using the VIP bus interface. The covered topics include the hardware platform a detailed description of the source-code modules and microcontroller-specific items.
AC-coupled circuits are often used for single supply operation to bring the input voltage into the inputrange of the amplifier. This circuit topology can be used in AC smoke detectors or in AC proximitysensors.
The first section of this 100-page book describes digital signal processing algorithms such as tone generation (including DTMF) voice compression/decompression (ADPCM) acoustic echo cancellation and caller-id used in telephony. The second section discusses each functional block of analog data and facsimile (fax) modem and provides descriptions of the processes within each block.
The OMAP device is built upon a dual-core architecture that consists of a TIARM925T MPU and a C55x DSP device. Both cores have access to internal memory via an internal memory interface (IMIF) as well as external memory via two external memory interfaces namely the EMIF Slow (EMIFS) and EMIF Fast (EMIFF). This application report focuses on the ARM side of the device and investigates the

The TPS54160 is normally used as a buck voltage regulator. In these applications a lower dc voltage is derived from a higher input voltage. The output voltage is regulated by the internal current mode control circuitry to maintain a constant voltage over varying line and load conditions. The TPS54160 is not limited to use in the standard buck topology. This application report demonstrates
