Abstract
Associative keys and retrieve outputs corresponding thereto are registered to an associative memory in a vector data conversion apparatus. Conversion vector data stored in the main storage and comprising vector elements of the same type of an associative key is sequentially read out for each vector element and is inputted to a comparator, which then compares the vector element with the associative keys beforehand registered to the associative memory so as to determine whether or not a matching condition exists therebetween. When the comparator detects the matching condition, a retrieve output corresponding to the matched associative key is read out from the associative memory and is stored in the main storage. While the conversion vector data is sequentially read out for each vector in this manner, the retrieve output data is sequentially stored in the main storage so as to generate the converted vector data comprising the retrieve output data as vector elements. A user identifier may also be inputted as a compare element together with the associative key, thereby preventing an erroneous data conversion from taking place even when a plurality of users share the vector data conversion apparatus.
