ARC Temperature Sensing Calibration Platform

In this contest, we aim to develop a machine learning method to calibrate the thermal sensor and to avoid the interference from the environment for higher accuracy level in temperature measurement.The computation complexity of our proposed method would be suitable for porting on to the ARC Embedded Starter Kit platform.


In most acedemic research, most of those fabricated chips are verfied through testing machine to check the input and output pattern's functionality. However for sensor design, we need a platform to check the functionality.

Due to the process variation , sometimes our chip may not work as well as we do in our post-layout-simulation. So during system integration, we still need some software method (using some Machine Learning Algorithm) to calibrate the chip's functionality.

Therefore we adopt ARC Embedded Stater Kit as our platform to build up our system prototype.

  • Main Task Of Our Platform
    • Data Extraction
    • Chip Sensor Functionality Calibration


Phase1: Data Extraction

Using ARC EMSK to build up the temperature monitor system to collect all the chip's response data in the testing chamber. All the data collected from EMSK would transmitted through UART inteface back to PC for analysis.

Phase2: Data Analysis & Algorithm Selection

After data preprocessing, we could divide those raw-data into training set and testing set, and start to build up our Machine Learning Model to get better temperature accuracy.

Phase3: Porting ML model to ARC EMSK Platform

Currently we only developed the Terminal Display Version Porting the Inference Part of our Machine Learning Model to the ARC EMSK platform and start to check our functionality of our ML model to boost up the accuracy.
