  • Multiple port shared memory
    Patent number: 9627014
    Abstract: Some of the embodiments of the present disclosure provide a system comprising: a shared memory unit and an arbiter that is configured to generate a clock signal, receive information regarding bandwidths of each of a plurality of agents, and determine a clock frequency or a sequence for selecting single agents among the plurality of agents to allow the single agents to transfer data in parallel from/to the shared memory unit in a single clock cycle of the clock signal, wherein the sequence is based, at least in part, on the bandwidths for each of a plurality of agents. The arbiter is also configured to cycle through the determined sequence for selecting the single agents among the plurality of agents to allow the single agents to transfer data from/to the shared memory unit in the single clock cycles.
    Type: Grant

  • Method and apparatus for selectively deskewing data traveling through a bus
    Patent number: 7328362
    Abstract: A method for selectively deskewing data traveling through a bus in a network device is disclosed. Bit-level data is received from each data line of a plurality of data lines of the bus. Vertical line information is detected for the plurality of data lines to determine if there is a match with a training pattern. A skew distance is calculated once there is a match with the training pattern. Then, the plurality of data lines are bit aligned based on the skew distance.
