AI High Performance Computing - AI Chip Design

The simplest and most direct design approach for AI chips is to directly map neurons to hardware chips, as shown in the figure. The Full Hardware Implementation scheme maps each neuron to a logical computing unit and each synapse to a data storage unit. This architecture design can achieve a high-performance and low-power AI chip, such as an Intel ETANN chip. In the full hardware implementation scheme, the output data of the previous layer is multiplied by the weight, and the results of the multiplication are then added up, and then output to the next layer for calculation through an activation function. This architecture design tightly couples computing and storage, allowing the chip to avoid large-scale data access while performing high-speed computing, improving overall computing performance while also reducing power consumption.

AI High Performance Computing - AI Specific Chip

Currently, artificial intelligence (AI) computing mainly refers to neural network algorithms represented by deep learning. Traditional CPUs and GPUs can be used to perform AI algorithm operations, but they are not designed and optimized for deep learning characteristics, so they cannot fully adapt to AI algorithm characteristics in terms of speed and performance. Generally speaking, AI chips refer to ASICs (specialized chips) specially designed for AI algorithm characteristics.
