发明名称 Routing structures for a tileable field-programmable gate array architecture
摘要 A field-programmable gate array (FPGA), comprising: a first FPGA tile, the first FPGA tile comprising a plurality of functional groups (FGs), a regular routing structure, and a plurality of interface groups (IGs). The plurality of FGs are arranged in rows and columns with each of the FGs being configured to receive regular input signals, perform a logic operation, and generate regular output signals. The regular routing structure is coupled to the FGs and configured to receive the regular output signals, route signals within the first FPGA tile, and provide the regular input signals to the FGs. The plurality of IGs surround the plurality of FGs such that one IG is positioned at each end of each row and column. Each of the IGs is coupled to the regular routing structure and configured to transfer signals from the regular routing structure to outside of the first FPGA tile. The first FPGA tile also comprising a secondary routing structure independent of the regular routing structure, coupled to each of the IGs, configured to transfer signals from said first FPGA tile to at least one other FPGA tile. The disclosed apparatus also provides for a routing structure between IGs and RAM blocks. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understand that it will not be used to interpret or limit the scope or meaning of the claims.
