AI high-performance computing - integrated storage and computing

Integrated storage and computing or in memory computing is the complete integration of storage and computing, directly utilizing memory for data processing or computation. Under the traditional von Neumann architecture, data storage and computation are separated. Due to the increasing performance gap between storage and computation, the speed at which the processor accesses stored data is much lower than the processor's computation speed. The energy consumption of data transportation between memory and main memory is also much higher than the energy consumed by the processor's computation.

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.
