Abstract

An integrated circuit device may include programmable logic fabric disposed on a first integrated circuit die, such that the programmable logic fabric may include a first region of programmable logic fabric and a second region of programmable logic fabric. The first region of programmable logic fabric is configured to be programmed with a circuit design that operates on a first set of data. The integrated circuit may also include network on chip (NOC) circuitry disposed on a second integrated circuit die, such that the NOC circuitry is configured to communicate data between the first integrated circuit die and the second integrated circuit die.

Claims (36)
