New RED-PIM technique slashes transformer latency via in-memory processing

Researchers have developed RED-PIM, a novel algorithm-architecture co-design aimed at improving the efficiency of transformer models. This approach addresses the significant data movement bottleneck in transformers by performing computations directly within memory, a technique known as Processing-In-Memory (PIM). RED-PIM specifically targets the attention operations, reducing inter-bank data movement and shrinking intermediate matrices to minimize latency and computation cost. The system demonstrates substantial inference time reductions, with gains up to 99.99% on longer sequences and significant performance improvements on real-world datasets while maintaining accuracy.
