Multichannel memory arbitration and interleaving scheme

A method, comprising:

• receiving a memory request from a peripheral;
• placing one or more portions of the received memory request in a memory channel queue of a set of memory channel queues associated with the peripheral;
• selecting the memory channel queue using an arbitration algorithm, wherein the memory channel queue is selected based on at least one of a load level of the memory channel associated with the set of memory channel queues and a length of time a portion of the received memory requests have been in a memory channel queue;
• presenting the one or more portions of the received memory request in the selected memory channel queue to a second arbitration module for selection by the second arbitration module;
• and
• outputting the presented one or more portions of the received memory requests based on the selection by the second arbitration module.

A memory controller comprising:

• a set of memory channel queues, wherein memory channel queues of the set of memory channel queues correspond to memory channels to access a set of memory modules, and wherein the set of memory channel queues are associated with a peripheral;
• a first arbitration module;
• a second arbitration module;
• and
• a register;
• wherein the memory controller is configured to:
• receive a first memory request from the peripheral;
• place one or more portions of the first memory request in the memory channel queues of the set of memory channel queues;
• wherein the first arbitration module is configured to:
• determine an arbitration algorithm based on information in the register;
• select a first memory channel queue based on the arbitration algorithm;
• present the one or more portions of the first memory request in the selected first memory channel queue to the second arbitration module;
• and
• output the presented one or more portions of the first memory request based on a selection by the second arbitration module.
