Publication number: 20230289309Abstract: Integrated circuit packages with multiple integrated circuit dies are provided. A multichip package may include a substrate, a main die that is mounted on the substrate, and multiple transceiver daughter dies that are mounted on the substrate and that are coupled to the main die via corresponding Embedded Multi-die Interconnect Bridge (EMIB) interconnects formed in the substrate. Each of the main die and the daughter dies may include configurable adapter circuitry for interfacing with the EMIB interconnects. The adapter circuitry may include FIFO buffer circuits operable in a 1x mode or 2x mode and configurable in a phase-compensation mode, a clock-compensation mode, an elastic mode, and a register bypass mode to help support a variety of communications protocols with different data width and clocking requirements. The adapter circuitry may also include boundary alignment circuitry for reconstructing (de)compressed data streams.Type: ApplicationFiled: April 24, 2023Publication date: September 14, 2023Inventors: Huy Ngo, Keith Duwel, David W.

Publication number: 20220190843Abstract: 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.Type: ApplicationFiled: July 26, 2021Publication date: June 16, 2022Inventors: David W.

Patent number: 11115025Abstract: The present disclosure relates to modular transceiver-based network circuitries that may include internal configurable interfaces or gaskets. The configurable gaskets may facilitate integration of the network circuitries in electronic devices by providing a transparent interface to processing circuitries coupled to the network circuitries. Moreover, the configurable gaskets may also have a floorplan layout (e.g., a chiplet layout) that may facilitate coupling of multiple network circuitries to a single processing circuitry, in a modular manner.Type: GrantFiled: March 29, 2018Date of Patent: September 7, 2021Assignee: Intel CorporationInventors: Sergey Y.

Patent number: 10699045Abstract: The present embodiments relate to regulating the supply voltage of an integrated circuit. The integrated circuit may implement a circuit design. The circuit design implementation may meet timing constraints with timing margins when operated with the integrated circuit at a nominal supply voltage level. The integrated circuit may further include a voltage identification controller. The voltage identification controller may determine a reduced voltage level based at least on the timing margins such that operating the circuit design implementation with the integrated circuit meets timing constraints. The voltage identification controller may direct a voltage regulator, which may be included in the integrated circuit or located outside the integrated circuit, to reduce the supply voltage level from the nominal supply voltage level to the reduced voltage level, thereby reducing the power consumption of the integrated circuit.Type: GrantFiled: August 2, 2018Date of Patent: June 30, 2020Assignee: Altera CorporationInventors: David W.
