<P>PROBLEM TO BE SOLVED: To allow a memory controller to reduce emphasis on QoS parameters and to increase emphasis on memory bandwidth optimization as operations flow through a memory controller pipeline. <P>SOLUTION: In an embodiment, a memory controller includes multiple ports. Each port may be dedicated to a different type of traffic. In an embodiment, quality of service (QoS) parameters may be defined for the traffic types, and different traffic types may have different QoS parameter definitions. The memory controller may be configured to schedule operations received on the different ports based on the QoS parameters. In an embodiment, the memory controller may support upgrade of the QoS parameters when subsequent operations are received that have higher QoS parameters, via sideband request, and/or via aging of operations. <P>COPYRIGHT: (C)2012,JPO&INPIT |
