AN-1943 Understanding Serial Digital Video Bit Rates (Rev. A)
Texas InstrumentsThe objective of this application report is to explain the basis for the bit rates used in serial digital interface (SDI). This leads to a deeper intuitive understanding of the nature of the SDI signal and will ultimately help the engineer design robust serial digital video systems.
Characterizing Audio Amplifier Thermal Performance
Texas InstrumentsThis application report discusses how to accurately measure the thermal performance of an audio amplifier IC at the system level.
Running a TMS320C64x+ Codec Across TMS320C64x+ Based DSP Platforms
Texas InstrumentsThis application report describes the device differences to be taken care for running the C64x+™ video codec software on different C64x+ based platforms. This document assumes that the codec software is developed for the C64x+ digital signal processor (DSP) core. As many TI platforms have a C64x+ DSP this document gives the details for running the standalone codec software on a C64x+ platfo
Q-Values in the Watch Window
Texas InstrumentsDigital signal processor (DSP) architectures are designed to handle finite number precision. Compared to floating point architecture fixed-point DSPs offer a limited degree of precision but are usually more cost effective and offer far superior performance.To work with fixed-point formats programmers need to take into consideration that each of the numerical operations should avoid overflo
In-System Programming With Catalog TMS470 Devices (Rev. A)
Texas InstrumentsThis document gives two examples of reprogramming the flash memory in-system on the TMS470 devices. These examples are intended as a reference to enable users to create their own in-system programming (ISP) methods. The reference design includes TMS470 software for use with the IAR Embedded Workbench tool. NOTE: The examples in this application report require the Flash API Modules (

Fast Logarithms on a Floating-Point Device
Texas InstrumentsThis document discusses a fast way to calculate logarithms (base 2) on a TMS320C30 or TMS320C40. This TMS320C30/C40 function calculates the log base two of a number in about half the time of conventional algorithms. The method can easily be scaled for faster execution if less accuracy is desired. The mathematics of the function is discussed in detail. There are plots to determine accuracy at diffe
JPEG Motion on the DM642 EVM (Rev. A)
Texas InstrumentsThis software demonstration combines real−time D1 Joint Photographic Experts Group (JPEG) encoding and decoding of images on the DM642 Evaluation Module (EVM) with networking functionality.
The JPEG standard pertains to compression of still images. Performing JPEG compression at the rate of 30 frames per second in isolation as individual images is known as motion JPEG (MJPEG). This demon
UCC28070 300W Interleaved PFC Pre-regulator Design Review (Rev. B)
Texas InstrumentsIn higher power applications to utilize the full line power and reduce line current harmonics PFC Pre-regulators are generally required. In these high power applications interleaving PFC stages can reduce inductor volume and reduce input and output capacitor ripple current. This results in smaller overall magnetic volume and filter capacitor volume increasing the converters overall power density.
