摘要： A method and apparatus for detecting a queue depth of a memory queue in a memory system is described. The method includes estimating a start position of the queue by examining a portion of a queue start identifier of the memory queue, estimating an end position of the queue by examining a portion of a queue end identifier of the memory queue, and utilizing the start position and the end position to estimate the queue depth of the memory queue. The apparatus applies the method. One embodiment of the method and apparatus may be suitable for implementation on look-up tables of field general programmable gate arrays.

摘要： Bounding cell reorder depth is disclosed. It is determined whether a reorder buffer that is associated with a switch fabric exceeds a depth limit. In the event that the reorder buffer exceeds the depth limit, backpressure with respect to a source associated with the reorder buffer is sent. In such cases source based back pressure information is included in a reserved field in a cell that is being sent into the switch fabric. In the event that the reorder buffer does not exceed the depth limit, the cell is sent to the switch fabric. In such cases the reserved field is present in the cell but is unused.
