**Table 1** Interfaces provided by KVecTurbo
API	Function
ComputePQTable	Calculates the PQ codebook.
ComputeVectorPQCode	Quantizes the input vector based on the PQ codebook.
GetPQDistanceTableSdc	Calculates the PQ SDC distance table, that is, calculates the distance between the cluster centroids in each subspace.
GetPQDistanceTableAdc	Calculates the PQ ADC distance table, that is, calculates the distance between the query vector and the cluster centroids in each subspace.
GetPQDistance	Calculates the PQ ADC or SDC distance. If querycode == NULL, the ADC distance is calculated. If querycode != NULL, the SDC distance is calculated.
