D-NOVA: In-Storage Retrieval Accelerator via Dual-Bound 3D NAND-Optimized Similarity Search with Vector Adaptation
D-NOVA is a hardware-software co-designed in-storage retrieval accelerator that executes an inverted file (IVF)-based hierarchical retrieval pipeline by deeply embedding the search functionality directly into the NAND memory array, and introduces a lightweight contrastive adapter that maps embedding vectors into a DTS-...
