摘要： In one embodiment, a method determines a plurality of categories for requests for a shared resource being shared by a plurality of entities. A request for the resource is received from an entity in the plurality of entities. The method determines a category in the plurality of categories for the received request. If the received request is determined to be in a first category, the method dispatches the received request to a first arbitration scheme configured to determine an arbitration decision in a first time cycle. If the received request is determined to be in a second category, the method dispatches the received request to a second arbitration scheme configured to determine an arbitration decision in a second time cycle of a different length from the first time cycle.

摘要： Systems and methods for timing read operations with a memory device are provided. A timing signal is received from the memory device at a gating circuit. The timing signal is passed through as a filtered timing signal during a gating window. The gating window is configured to open the gating window based on a control signal and to close the gating window based on a failing edge of the timing signal. The falling edge is determined based on a counter that is triggered to begin counting by the control signal. The control signal is generated at a timing control circuit after receiving a read request from a memory controller. The timing control circuit is configured to delay generation of the control signal to cause the gating window to open during a preamble portion of the timing signal.

摘要： System and methods are provided for dynamically managing a first-in/first-out (FIFO) command queue of a system controller. One or more commands are received into the command queue, a command being associated with a priority parameter. A current command first in line to be executed in the command queue is determined, the current command being associated with a first priority parameter. A second command associated with a second priority parameter is determined, the second priority parameter being largest among priority parameters associated with the one or more commands. A final priority parameter for the current command is computed based at least in part on the second priority parameter.
