Real-time ASCEND

This article is about planned development or proposed functionality. Comments welcome.

We propose developing a system that allows realtime data to be incorporated into ASCEND simulations, both for computing the performance of realtime systems, as well as for performing realtime parameter estimation. This is a huge area, and work is just beginning.

Integration of live data streams into ASCEND simulation

Detailed procedure

Please scroll down through the page to understand the overall work-flow diagram of current work.

Sub-pages:

• Data acquisition (DA) hardware
• Real-time Data reader
• Real-time solver

Quick example

Following video demonstrate calculation of average of two live real-time temperature feeds. Please visit detailed procedure to learn more about real-time data reader and prototype of real-time solver.
