  • Patent number: 12294368
    Abstract: The present disclosure is directed to 3-D stacked architecture for Programmable Fabrics and Central Processing Units (CPUs). The 3-D stacked orientation enables reconfigurability of the fabric, and allows the fabric to function using coarse-grained and fine-grained acceleration for offloading CPU processing. Additionally, the programmable fabric may be able to function to interface with multiple other compute chiplet components in the 3-D stacked orientation. This enables multiple compute components to communicate without the need for offloading the data communications between the compute chiplets.

  • Patent number: 12273107
    Abstract: Embodiments of the present disclosure are related to dynamically adjusting a timing and/or power model for a programmable logic device. In particular, the present disclosure is directed to adjusting a timing and/or power model of the programmable logic device that operates at a voltage level that is not other than a predefined voltage defined by a voltage library. A system of the present disclosure may interpolate between voltage levels defined by the voltage libraries to generate a new voltage library for the programmable logic device. A timing and/or power model may be generated for the programmable logic device based on the new voltage library and the programmable logic device may be analyzed using the timing and/or power model at the interpolated voltage. The timing and/or power model may be used to generate a bitstream that is used to program the integrated circuit.

  • Patent number: 12266625
    Abstract: An integrated circuit includes a package substrate that includes first and second electrical traces. The integrated circuit includes first, second, third, and fourth configurable dies, which are mounted on the package substrate. The first and second configurable dies are arranged in a first row. The third and fourth configurable dies are arranged in a second row, which is approximately parallel to the first row. The first and third configurable dies are arranged in a first column. The second and fourth configurable dies are arranged in a second column, which is approximately parallel to the first column. The first electrical trace couples the first and third configurable dies, and the second electrical trace couples the second and third configurable dies. The second electrical trace is oblique with respect to the first electrical trace. The oblique trace improves the latency of signals transmitted between dies and thereby increases the circuit operating speed.

  • Patent number: 12216150
    Abstract: A method includes mapping an aging measurement circuit (AMC) into the core fabric of an FPGA and operating the AMC for a select time period. During the select period of time, the AMC counts transition of a signal propagating through the AMC. Timing information based on the counted transitions is stored in a timing model in a memory. The timing information represents an aging characteristic of the core fabric at a time that the AMC is operated. An EDA toolchain uses the timing information in the timing model to generate a timing guard-band for the configurable IC die. The AMC is removed from the core fabric and another circuit device is mapped and fitted into the core fabric using the generated timing guard-band models. The circuit device is operated in the configurable IC die based on the timing guard-band models.

  • Patent number: 12206410
    Abstract: A programmable device may have logic circuitry formed in a top die and memory and specialized processing blocks formed in a bottom die, where the top die is stacked directly on top of the bottom die in a face-to-face configuration. The logic circuitry may include logic sectors, logic array blocks, logic elements, and other types of logic regions. The memory blocks may include large banks of multiport memory for storing data. The specialized processing blocks may include multipliers, adders, and other arithmetic components. The logic circuitry may access the memory and specialized processing blocks via an address encoded scheme. Configured in this way, the maximum operating frequency of the programmable device can be optimized such that critical paths will no longer need to traverse any unused memory and specialized processing blocks.

  • Patent number: 12026008
    Abstract: An integrated circuit die includes input buffer circuits that are enabled during an input mode of operation in response to first control signals to transmit input signals into the integrated circuit die from conductive bumps. Each of the input buffer circuits is coupled to one of the conductive bumps. The integrated circuit die also includes output buffer circuits that are each coupled to one of the conductive bumps. The output buffer circuits are enabled during an output mode of operation in response to second control signals to transmit output signals from the integrated circuit die to the conductive bumps. The input buffer circuits are disabled from transmitting signals during the output mode of operation in response to the first control signals. The output buffer circuits are disabled from transmitting signals during the input mode of operation in response to the second control signals.

  • Patent number: 12007929
    Abstract: A processor having a system on a chip (SOC) architecture comprises one or more central processing units (CPUs) comprising multiple cores. An optical Compute Express Link (CXL) communication path incorporating a logical optical CXL protocol stack path transmits and receives an optical bit stream directly after the link layer, bypassing multiple levels of the CXL protocol stack. A CXL interface controller is connected to the one or more CPUs to enable communication between the CPUs and one or more CXL devices over the optical CXL communication path.

  • Patent number: 11983135
    Abstract: Embodiments herein relate to systems, apparatuses, or processes for improving off-package edge bandwidth by overlapping electrical and optical serialization/deserialization (SERDES) interfaces on an edge of the package. In other implementations, off-package bandwidth for a particular edge of a package may use both an optical fanout and an electrical fanout on the same edge of the package. In embodiments, the optical fanout may use a top surface or side edge of a die and the electrical fanout may use the bottom side edge of the die. Other embodiments may be described and/or claimed.

  • Patent number: 11915996
    Abstract: An integrated circuit structure that includes a first integrated circuit package and a second integrated circuit package is described. The two packages can be stacked above, for example, a printed circuit board. The top package is inverted, such that a first die of that top package is facing a second die of the bottom package. A cooling arrangement is in a gap between the first and second integrated circuit packages, and is thermally coupled to the first and second die. The cooling arrangement is to transfer heat generated by a first die of the first integrated circuit package and a second die of the second integrated circuit package. In some cases, structures comprising electrically conductive material (e.g., metal) are encapsulated by a molding compound or insulator, and extend between a first substrate of the first integrated circuit package and a second substrate of the second integrated circuit package.
