A general-purpose intelligent search agent on the Internet has been developed using VLSI Associative Processor (AP)chips as the hardware accelerator.The agent performs similarity-based search in a large volume of database.Although he similarity-based search processing is compu ationally very expensive,latency free search has become possible due to the highly parallel maximum-likelihood search architecture of he AP chip. In this study,we search schemes are proposed for Intelligent Internet search agents:the server-based solution and the client-based solution.The architecture of the AP chip has been optimized for each of the solutions and their performances are compared.In the server-based solution in which multiple AP chips are mounted on a printed board in the server,10,000 simultaneous accesses o he intelligent search agent are allowed wi h a response time of less than 1 sec for all visitors.This is by no means possible in software solu ions.In he client solu ion,on the other hand,in which a single AP chip is embedded in a personal compu er,a person can enjoy a very comfor able interactive preference search all in a response time of about 10 -4 sec.As an example of similarity-based intelligent search,an E-commerce real-estate agent system has been developed using he AP chip implemented in field-programmable gate arrays (FPGA)and the effectiveness of such agent systems has been demonstrated.
