ABSTRACT:
A MAC architecture for WLAN stations partitions functionality between a software-based MAC component and a hardware-based MAC component that work together to balance function and performance. In general, the fulcrum for this balance centers on timing requirements. Accordingly, the hardware-based MAC component is designed to handle many of the functions that are processor-intensive and/or must be performed under strict timing constraints. The software-based MAC component is designed to handle many of the functions that are memory-intensive, but present more lenient timing requirements. The software-based MAC component may be configured to provide an efficient and robust interface to the hardware-based MAC component. In particular, the software-based MAC component may format and prioritize packets to be sent over the air interface, and generate a command structure that provides instructions for the hardware-based MAC component to process the packet.
