« Do you have a recent NVidia graphic card with Raytracing (RTX) ? If yes chances are your GPU embeds a TPU (Tensor Processing Unit) to accelerate the RayTracing with machine learning (Deep Learning Super Sampling,
DLSS). OK, enough of acronyms, and let's dive deep in what those Tensor Process Unit are, with an in depth explanation of what is inside the now legacy first version. Back in the days Google really though out of the box to tackle energy efficiency for Machine Learning. With for example 8 bits registers, and a way of loading registers in matrix multiplication unit inspired from biology: the "systolic array". From the article: "The design is called systolic because the data flows through the chip in waves, reminiscent of the way that the heart pumps blood". »
