The relevance of the Semantic Web has been increased steadily over the recent years. This can be shown by the increasing number of developed and used Semantic Web tools and applications.The main idea of the Semantic Web is to consider the semantic of symbols to enable a more precise machine processing. For this purpose, the necessary links between data sets are stored in database systems. The continuously increasing size of the data sets leads to performance issues for traditional databases and even specialized Semantic Web databases. In the scope of Semantic Web databases data sets with billions of entries are available and processing of these data sets on software-based solutions is highly time consuming.Thus, in this project a hardware/software system will be investigated and developed to outsource time consuming tasks to a programmable logic chip (FPGA, Field Programmable Gate Array). The hardware acceleration of cost intensive tasks will cover the index generation as well as query processing in Semantic Web databases. During query processing the determination of which function should be mapped to the FPGA will be decided at runtime. As the mapping of the data path to the basic elements uses partial runtime reconfiguration, an optimal hardware accelerator can be provided for any query.
