  • Processor socket bridge for input/output extension
    Patent number: 11604755
    Abstract: Presented herein are improvement to computer system architecture. In one embodiment, a method includes reconfiguring system interconnect links disposed between a first central processing unit socket and a second central processing unit socket, disposed together on a single motherboard, as peripheral bus links; and transmitting electrical signals, via the peripheral bus links, and via a printed circuit board that bridges the second central processing unit socket, to at least one input/output functional block that is disposed on the single motherboard and that is selectively connectable to the second central processing unit socket.
    Type: Grant
    Filed: March 9, 2021
    Date of Patent: March 14, 2023
    Assignee: CISCO TECHNOLOGY, INC.
    Inventors: Jayaprakash Balachandran, Bidyut Kanti Sen, Kenny Lieu, Dattatri N. Mattur

  • Multi-column interleaved DIMM placement and routing topology
    Patent number: 11004476
    Abstract: In one embodiment, a printed circuit board (PCB) has a first central processing unit (CPU) socket and a second CPU socket substantially in line with the first CPU socket, and also has a first plurality of dual in-line memory module (DIMM) sockets interconnected with the first CPU socket and a second plurality of DIMM sockets interconnected with the second CPU socket (in a direction parallel to the first plurality of DIMM sockets). The first plurality of DIMM sockets are arranged on the PCB in at least a first column and a second column of DIMM sockets, and the second plurality of DIMM sockets are arranged on the PCB in at least the second column and a third column of DIMM sockets, such that the second column of DIMM sockets contains interleaved DIMM sockets from each of the first plurality of DIMM sockets and the second plurality of DIMM sockets.
