If vectors are normalized to length 1 (like OpenAI embeddings), use inner product for best performance.SELECT * FROM items ORDER BY embedding <#> '[3,1,2]' LIMIT 5;Approximate SearchTo speed up queries with an IVFFlat index, increase the number of inverted lists (at the expense of ...
FX`LENGTH-1的值为FX这个信号的长度减1；TMP:STD_LOGIC_VECTOR(FX`LENGTH-1 DOWNTO 0)则表示声明一个TMP信号，它是一个向量，长度为FX`LENGTH，标号从FX`LENGTH-1到0
Bitwidth can be upgraded automatically. For theVector<T>type, its length is not fixed, but is the same as the longest vector register for that processor. Specifically, if the CPU supports the AVX instruction set (strictly AVX2 and above), theVector<T>type is 256 bits; if the CPU only ...
