  • Method and apparatus for managing flow control in PCI express transaction layer
    Patent number: 7698477
    Abstract: A method and apparatus is provided wherein a central Credit Controller Entity (CCE) is connected to a PCIE fabric environment by means of several buses. Flow Control information sent to the CCE over two of the buses indicates the buffer storage capacity that is available at respective Receiver components in the PCIE fabric. The CCE processes the Flow Control information, to generate updates that are sent by a third bus to Transmitter components corresponding to the Receivers. In one useful embodiment, directed to a method of Flow Control management, the CCE provides a repository adapted to store credit count information that represents the available storage capacity of respective Receivers. The method further comprises routing further credit count information from a given Receiver to the CCE, for storage in the repository, following each of successive events that affect the storage capacity of the given Receiver.

  • Configurable, fast, 32-bit CRC generator for 1-byte to 16-bytes variable width input data
    Patent number: 7571370
    Abstract: A method and circuit for performing CRC calculations permits variable width data input. Preferably, multiple CRC calculations are performed in parallel, each CRC calculation involving a different number of data bits from the data word and terminating within one clock cycle. The CRC polynomial is preferably incorporated into the hardware for each CRC calculation.
