Acoustic Echo Cancellation Algorithms and Implementation on the TMS320C80
Texas InstrumentsAcoustic echo cancellation on the TMS320C8x multiprocessor digital signal processor (DSP) offers high performance and flexibility to meet varying user needs. This document describes the implementation of an integrated N-tap digital acoustic echo canceller on the TMS320C8x parallel processor (PP). A brief discussion of a generic echo cancellation algorithm is provided. A 512-tap (64-ms span) echo
TVP5020 NTSC/PAL Video Decoder Programming for the I2C Host Interface
Texas InstrumentsThis application report provides a complete working example of a C-language program to initialize the video decoder using the I2C bus interface. This Example Initialization Program executes on the TVP56000EVM evaluation module featuring the TVP5020 video decoder and the TVP6000EVM hardware platform microcontroller-specific aspects and a detailed description of the source-code modules.
U-122 A New Family of Integrated Circuits Controls Resonant Mode Power
Texas InstrumentsThis application note introduces the UC3861-8 family of ICs which are optimized for the control of zero-current-switched and zero-voltage-switched quasi-resonant converters. Differences among members of this device family result from the various combinations of UVLO thresholds and output options. The one-shot pulse steering logic is configured to program either on time for ZCS systems (UC1865-186
