C Prototype

        
             aclfvQueryTable *aclfvCreateQueryTable(uint32_t queryCnt, uint32_t tableLen, uint8_t *tableData, uint32_t tableDataLen)

Python Function

        
             query_table = acl.fv.create_query_table(query_cnt, table_len, table_data, table_data_len)

query_cnt	Int, number of search requests, fixed at 1 in 1:N mode or up to 1024 in the N:M scenario.
table_len	Int, table length, fixed at 32 KB. The system verifies the length internally.
table_data	Int, feature value table, stored consecutively based on the feature length.
table_data_len	Int, length of the memory allocated to tableData, which is used for verification.
