Abstract
An apparatus includes a communication bus circuit, a memory circuit, a queue manager circuit, and an arbitration circuit. The communication bus circuit includes a command bus and a data bus separate from the command bus. The queue manager circuit may be configured to receive a first memory request and a second memory request, each request including a respective address value to be sent via the command bus. The first memory request may include a corresponding data operand to be sent via the data bus. The queue manager circuit may also be configured to distribute the first memory request and the second memory request among a plurality of bus queues. Distribution of the first and second memory requests may be based on the respective address values. The arbitration circuit may be configured to select a particular memory request from a particular one of the plurality of bus queues.
