Neural Engine - What is it ???

Well, we have noticed the presence of neural engine cores in Apple devices since 2017. If you're wondering about the purpose of this part of the microprocessor, this blog is for you.

A normal CPU processor works with serial data. It processes a calculation in a definite time and proceeds to another. A GPU works like multiple processors working simultaneously with different calculations. But with high power consumption. Both these chips can Run machine learning calculations. But a CPU will be slower than a GPU. 

In terms of speed, a neural engine is much faster than a GPU. Machine learning calculations are matrix additions and multiplications. We extract these matrix operations and run them on a separate dedicated circuitry. This circuitry is called a Neural engine. 

Modern phones/ computers have several AI functionalities built inside like image recognition, fingerprint sensing, GPS tracking etc. Normal processors and GPUs take too much power and time to perform these tasks. So employing a neural engine will help reduce work loads on Core processing units.
