In the system, a first module operating in a first protocol and a second module operating in a second protocol share one communication channel. An arbitration circuit schedules medium accesses thereof, in which a quota table maintains a utilization value updated in accordance with the amount of time slots consumed by a particular traffic type, and a time counter periodically resets the utilization value to a default value. When the arbitration circuit receives a request for medium access of the particular traffic type, the arbitration circuit grants the request according to the utilization value, such that the first module or the second module are not activated at the same time.

Abstract: A method for frame processing in a wireless network is provided. A receiver receives and forwards a frame to a forwarding logic unit. The forwarding logic unit receives the frame and decides to discard the frame, to forward the frame to a host interface, or to notify a firmware according to predefined forwarding rules. Thus the forwarding logic unit validates and directly forwards the frame to the host interface without firmware intervention.
