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.

Using the PGA Function in TSC210x/AIC26/AIC28/DAC26 Devices
Texas InstrumentsTI's touch screen and audio codec/DAC devices such as the TSC2100 TSC2101 TSC2102 TLV320AIC26 TLV320AIC28 and the TLC320DAC26 have one or more audio-band programmable gain amplifiers (PGA) in their input circuitry. This application report describes how to implement this PGA function using the TLV320DAC26 as an example.
Signal Processing Examples With C62x Digital Signal Processing Library (DSPLIB) (Rev. A)
Texas InstrumentsThe TMS320C62x™ digital signal processing library (DSPLIB) provides a set of C-callable assembly-optimized functions commonly used in signal processing applications e.g. filtering and transform. The DSPLIB includes several functions for each processing category based on the input parameter conditions to provide parameter-specific optimal performance. Therefore it is important to unders
Using CDC857/CDCV850 toTransform Single-End CLK Signal Into Differential Output
Texas InstrumentsThe CDC857 and the CDCV850 devices are PLL-based differential clock drivers with a maximum operational frequency of 167 MHz. These devices have been designed to support a double-data-rate (DDR) specification and therefore they have higher immunity against incoupling common mode noise. However they require a differential clock input signal.This report shows (a) how to convert a single ended cl
