zeroth

(jargon)
First.

Since zero is the lowest value of an unsigned binary integer, which is one of the most fundamental types in programming and hardware design, it is often natural to count from zero rather than one, especially when the integer is actually an index, as in hardware addressing or C and Lisp's 0-based indexing of arrays.

Hackers and computer scientists often like to call the first chapter of a publication "Chapter 0", especially if it is of an introductory nature (one of the classic instances was in the First Edition of K&R). In recent years this trait has also been observed among many pure mathematicians (who have an independent tradition of numbering from 0).

Zero-based numbering tends to reduce fencepost errors, though it cannot eliminate them entirely.

Logically, the next item after the zeroth should be the "oneth" but this is never used.

neural processing unit

Also called a "neuromorphic chip" and "intelligent processing unit" (IPU), a neural processing unit is designed to accelerate neural network processing. Such chips are expected to greatly accelerate the efficiency of artificial intelligence (AI) applications. In 2016, Qualcomm introduced its Zeroth Machine Intelligence Platform and Snapdragon Neural Processing Engine that enable mobile devices to run their own neural network models rather than going to the cloud. See TensorFlow, neural network and deep learning.

neuromorphic chip

A processor chip designed like the human brain rather than the traditional, sequential von Neumann architecture. Such chips are expected to greatly accelerate artificial intelligence (AI) applications in the future. In 2016, Qualcomm introduced its Zeroth Machine Intelligence Platform and Snapdragon Neural Processing Engine that enable mobile devices to run their own neural network models rather than going to the cloud.
