Abstract: The present invention discloses a system and a methodology for enhancing performance during wireless communications by reducing system latency, MIPS requirements and power consumption. The present invention discloses a system and method of wireless data communication in which part of upper layer stack processing is performed on a controller to relieve a host processor of some data intensive operations. After the initial connection establishment phase in which the controller retrieves certain information required for data transmission and stores the same locally, the data source provides data directly to the controller without routing the data through the host. The host is relieved of the data processing that needs to be done while the data is being transferred. Hence, the overall latency of the system is improved because of the optimal routing of data traffic. The host can even go to lower power modes while the controller is performing the data operations on behalf of the upper layer stack thereby saving power consumption of the overall system.
