Abstract

A field programmable gate array (FPGA) having hierarchical interconnect structure is disclosed. The FPGA includes logic heads that have signals routed therebetween by the interconnect structure. Each logic head includes a plurality of cascadable logic blocks that can perform combinatorial logic. The logic head can further be fractured into two independent logical units.
