  • Method and system for automatically controlling the insertion of control word in CPRI daisy chain configuration
    Patent number: 9392640
    Abstract: A method and apparatus automatically controls the insertion of information flow data over a shared CPRI link (561) by providing a hardware control mechanism (504-509) at a local radio base station subsystem (501) connected in a CPRI daisy chain configuration between a downstream RE device (570) and an upstream REC device (560) for determining whether the control word being transmitted is sourced from a downstream device (e.g., forwarded data from a downstream RE device) or from the local device.
    Type: Grant
    Filed: October 1, 2012
    Date of Patent: July 12, 2016
    Assignee: FREESCALE SEMICONDUCTOR, INC.

  • Communication steering for use in a multi-master shared resource system
    Patent number: 7415558
    Abstract: New approaches for providing communication between multiple masters (12, 14) and one or more shared resources (24, 30, 100) are needed. One example of a resource that may need to be shared is circuitry complying with the Universal Serial Bus (USB) standard (100). The USB specification defines the use of USB endpoints as data and control channels that reside in a USB device. In some cases it is desirable to have a certain number of endpoints controlled by one processor, and other endpoints controlled by a different processor, thus providing a shared control of all the endpoints. Circuitry (402, 417, 480) may be used to provide steering for additional signals such as interrupts. Other shared resources (24, 30) may use more centralized circuitry (36) to perform a steering function for additional signals.
