Adjustment of ESIOSC Oscillator Frequency (Rev. A)
Texas InstrumentsThe 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
Efficient Coding on the TMS320C5x
Texas InstrumentsAlgorithms 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
TMS320DM643x Pin Multiplexing Utility
Texas InstrumentsThe 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
A Tutorial on Optimizing Vision Algorithms on TI DSPs
Texas InstrumentsComputer vision algorithms are computationally intensive; tailoring them for a resource constrained embedded processor like DSP is challenging.
