Technical details and manufacturing context for Processing Element Array

Definition
The Processing Element Array is the core computational engine of a Neural Processing Unit, comprising numerous identical or specialized processing elements organized in a regular grid structure. This array enables massively parallel execution of neural network operations, particularly matrix multiplications and convolutions, by distributing computations across multiple processing elements simultaneously. Each element typically contains arithmetic logic units (ALUs), local memory, and interconnects for data exchange with neighboring elements.
Working Principle
The Processing Element Array operates by distributing neural network computations across its multiple processing elements in parallel. Input data (activations) and weights are broadcast or streamed to the array, where each processing element performs multiply-accumulate (MAC) operations on its assigned data subset. Results are aggregated through the array's interconnection network, enabling efficient execution of large matrix operations fundamental to neural network inference and training.
