Transformer models have become the cornerstone of numerous artificial intelligence applications, from natural language processing to computer vision and genomic sequence analysis. However, their immense success comes with a critical challenge: the high volume of data movement between processing units and memory during attention operations. This bottleneck limits the efficiency and scalability of Transformers, especially for long sequences where computational complexity grows quadratically.
To address this issue, Processing-In-Memory (PIM) technology emerges, enabling computations directly within memory, drastically reducing data transfer. Nevertheless, previous PIM implementations had significant limitations: costly inter-bank communication and scalability issues due to limited bank capacity. As a result, attention data had to be split across multiple banks, diminishing the potential benefits of PIM.
In this context, RED-PIM emerges as an innovative algorithm-architecture co-design that reduces Transformer latency. Its main approach is to minimize data movement between memory banks, reducing complexity from O(N²) to O(N), and shrinking intermediate attention matrices from N×N to d×d. Through intelligent reorganization of matrix operations, local computation, and an optimized data transfer strategy, RED-PIM significantly reduces computational cost and interconnect traffic.
Results are compelling: compared to baseline PIM implementations, RED-PIM achieves inference time reductions ranging from 16.05% to 99.99%, with a geometric mean of 66.42%. The most notable improvements occur in long sequences, where the data bottleneck is most severe. On real-world datasets, RED-PIM improves performance by 99.60% for long documents and 13.44% for shorter ones, while maintaining or even surpassing original model accuracy.
