INA117 Input Filtering The INA117 ±200V Difference Amplifier

The MSP430FR698x Extended Scan Interface (ESI) uses two clock sources. These clocks are ACLK and a high-frequency clock generated by the ESI oscillator ESIOSC. ESIOSC is realized as an RC-oscillator and shows a temperature and voltage dependency. However a hardware-supported measurement of ESIOSC frequency and adjustment by software allows compensating for the frequency drift. This application r

Algorithms based on dynamic programming techniques often make use of looped code conditional execution min-max searches and pointer addressing. The TMS320C5x core CPU allows zero-overhead looping multiple-condition branches delayed jumps and calls min-max instructions and post-modify indirect addressing to implement efficient search algorithms. This document discusses how to determine when

The DM643x devices use a great deal of internal pin multiplexing to allow the most functionality in the smallest and lowest cost package. The software accompanying this application report allows the pin multiplexing registers of the device to be calculated with ease as well as showing what peripherals can be used together and what devices of the DM643x family support the peripherals that are sele

Computer vision algorithms are computationally intensive; tailoring them for a resource constrained embedded processor like DSP is challenging. The performance improvements achieved by optimization can be huge. For example optimization of OpenCV's Pedestrian Detection on the C674x DSP improved the performance by a factor of > 200x. This application report is targeted towards engineers who develop
