ABSTRACT:
Integrated circuits having a compute-centric architecture. An integrated circuit may include an array of interconnected substantially similar logic blocks, each including a multiplier circuit and a lookup table circuit. The multiplier circuit has first and second inputs coupled to first and second data inputs of the logic block, and an output, and may include a non-uniform array of sub-circuits. The lookup table circuit has a first input coupled to a third data input of the logic block, a second input coupled to the output of the multiplier circuit, and an output coupled to a data output of the logic block. The multiplier circuits in adjacent logic blocks may be coupled together via a multi-bit partial product bus. Optional storage elements store the first and second inputs and the output of the multiplier circuit, the partial product bus, and the output of the lookup table circuit.
