Abstract: An interface bridge to enable communication between a first integrated circuit die and a second integrated circuit die is disclosed. The two integrated circuit die may be connected via chip-to-chip interconnects. The first integrated circuit die may include programmable logic fabric. The second integrated circuit die may support the first integrated circuit die. The first integrated circuit die and the secondary integrated circuit die may communicate with one another via the chip-to-chip interconnects using an interface bridge. The first and second component integrated circuits may include circuitry to implement the interface bridge, which may provide source-synchronous communication using a data receive clock from the second integrated circuit die to the first integrated circuit die.

Abstract: A seemingly monolithic interface between separate integrated circuit die may appear to be parallel or asynchronous from the perspective of the separate integrated circuit die. The signals of the seemingly monolithic interface, however, may actually be communicated between the separate die via serial and/or synchronous communication. In one method, a number of signals stored in a first parallel interface on a first integrated circuit die may be sampled. In some cases, at least one of the signals may be sampled more often than another one of the signals. A serial signal may be generated based on sampled signals. The serial signal may be transmitted to a corresponding second parallel interface on the second integrated circuit die.
