  • Publication number: 20220059491
    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.

  • Publication number: 20220014202
    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.

  • Publication number: 20210328589
    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.

  • Publication number: 20200402937
    Abstract: An integrated circuit package may be formed comprising an interposer with a center die and a plurality of identical integrated circuit dice positioned around the center die and attached to the interposer, wherein the center die is the switch/router for the plurality of identical integrated circuit dice. The interposer comprises a substrate, a central pattern of bond pads formed in or on the substrate for attaching the center die, and substantially identical satellite patterns formed in or on the substrate for attaching identical integrated circuit dice. The central pattern of bond pads has repeating sets of a specific geometric pattern and wherein the identical satellite patterns of bond pads are positioned to form the same geometric pattern as the specific geometric pattern of the central pattern of bond pads. Thus, substantially identical conductive routes may be formed between the center die and each of the identical integrated circuit dice.

  • Publication number: 20200357721
    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.
