UnverifiedFor a model with L layers and hidden dimension d, the KV Cache footprint for a single token is 2×L×d×sizeof(float16) bytes.66% similarUnverifiedPagedAttention divides the KV Cache into fixed-size blocks, with each block typically storing the key-value pairs of 16 tokens.64% similarVerifiedIn RAG practice, chunk_size is typically set between 256 and 1024 tokens, with an Overlap of approximately 10% to 20% retained.62% similarUnverifiedReal mode uses 16-bit registers and a segmented memory model, calculating a 20-bit physical address by shifting the 16-bit segment register left by 4 bits and adding a 16-bit offset, with an addressable space of only 1MB.59% similarUnverifiedPQ乘积量化通过切分向量、局部聚类、编码替代，可将向量存储体积压缩约8倍（四维示例中从16字节压缩到2字节）59% similar
