PipeMLLM System Overview
PipeMLLM is a real-time multimodal inference system for edge devices, designed to support temporal tasks under strict latency constraints. It adopts a pipelined sensing and encoding framework to enable overlapped data acquisition and processing, and integrates a decoding-aware multimodal configuration optimizer that selects sensing granularity and model complexity per modality. The optimizer also accounts for dynamic decoding latency introduced by foundation models, ensuring end-to-end efficiency.
Pipelined Sensing and Encoding Framework
PipeMLLM decomposes the unimodal encoding process into a sequence of fine-grained processing units, each responsible for encoding a localized segment of the input data. This allows encoding to begin incrementally as data arrives, reducing latency and memory usage. Encoded features are then aggregated to form temporal representations for fusion. This decomposition enables parallel execution of sensing and encoding across modalities and time, effectively hiding latency within sensing intervals and reducing idle wait time. A lightweight temporal aggregation module, using Alternating Temporal Shift and Temporal Difference Features, mitigates accuracy loss from reduced temporal context.
Decoding-aware Multimodal Configuration
The decoding-aware multimodal configuration optimizer selects sensing granularity and model complexity for each modality, while also considering decoding latency in foundation model-based systems. It performs offline profiling to build a latency table and train an accuracy predictor, and conducts online greedy search to select per-modality configurations that meet the overall latency constraint. It uses lightweight accuracy predictors based on Modality Consistency and Modality Complementarity, avoiding reliance on full sensor input or large fusion models. Dynamic Latency Constraint for LLM Decoding allows PipeMLLM to adapt to variable LLM decoding times by separating the latency budget into encode and decode components, ensuring overall system stays within budget.
