Patent number: 10938600Abstract: The present disclosure discloses a distributed system. The distributed system includes a plurality of radio heads and a plurality of controllers disposed in one or more chassis external to the plurality of radio heads. Each of the plurality of controllers includes a baseband unit (BBU), an uplink time-division multiplexing (TDM) switch and a downlink TDM switch. The uplink TDM switch and the downlink TDM switch forward data bits between a radio head and a BBU by using TDM cells which may reduce latency relative to using Ethernet frames.Type: GrantFiled: January 30, 2019Date of Patent: March 2, 2021Assignee: Cisco Technology, Inc.Inventors: David S.

Patent number: 9665522Abstract: An embodiment integrates non-PCI compliant devices with PCI compliant operating systems. A fabric system mimics the behavior of PCI. When non-PCI compliant devices do not know how to respond to PCI enumeration, embodiments provide a PCI enumeration reply and thus emulate a reply that would typically come from a PCI compliant device during emulation. Embodiments allow system designers to incorporate non-standard fabric structures with the benefit of still using robust and mature PCI infrastructure found in modern PCI compliant operating systems. More generally, embodiments allow an operating system compliant with a first standard (but not a second standard) to discover and communicate with a device that is non-compliant with the first standard (but possibly is compliant with the second standard). Other embodiments are described herein.Type: GrantFiled: January 12, 2015Date of Patent: May 30, 2017Assignee: Intel CorporationInventors: Bruce L. Fleming, Achmed R. Zahir, Arvind Mandhani, Satish B. Acharya

Patent number: 9164938Abstract: Methods and apparatus for integrating ARM-based IPs in computer system employing PCI-based fabrics. An PCI-based fabric is operatively coupled to an ARM-based ecosystem employing an ARM-based fabric such as OCP, AHB, or BVCI via a corresponding fabric-to-fabric bridge. Transactions between IP operatively coupled to the PCI-based fabric and IP in the ARM-based ecosystem are facilitated by applying applicable ordering and conversions operations via the fabric-to-fabric bridge and/or fabrics. For example, posted writes originating from IP coupled to the PCI-based fabric are converted to non-posted writes and serialized via the fabric-to-fabric bridge and forwarded to the ARM-based ecosystem.Type: GrantFiled: January 2, 2013Date of Patent: October 20, 2015Assignee: Intel CorporationInventors: Satish B.
