Abstract
Methods and apparatus are described for a data link control layer of a communication modem in which data movement functionality is implemented in hardware. In one embodiment, a data link layer comprises software, memory and hardware. The software comprises a processor configured to receive control signaling from a host device and provide control information to the hardware. The hardware comprises an outbound memory manager configured to receive data from the host device, determine locations in the memory for the data, store the data in the memory, determine which of the data is to be forwarded to a physical layer during a given transmit period, and forward the data to the physical layer. In preferred embodiments, the modem is a high performance modem designed for the terminals of a wireless local area network having multiple data flows, segmentation and reassembly, encryption, automatic repeat request, and quality of service requirements.
