20100002717 | Partitioned Medium Access Control Implementation - A novel implementation of a partitioned Medium Access Control (MAC) is disclosed. The illustrative embodiment employs a shared bus that typically is already present in a wireless terminal for communication between an Upper MAC and a Lower MAC. The partitioned MAC implementation therefore does not require any additional communication means between the Upper MAC and Lower MAC, resulting in a lower-cost system. In addition, the Upper MAC and Lower MAC pass native data structures by reference over the shared bus, thereby eliminating the need for drivers to coordinate communication via interrupts, handshaking, etc. The partitioned MAC implementation results in a cost-effective distributed architecture in which the Upper MAC resides in the terminal's host processor and the Lower MAC resides in the terminal's wireless station. | 01-07-2010 |

20110182300 | Network Traffic Shaping for Reducing Bus Jitter on a Real Time Controller - System and method for controlling access to a bus. A Network Interface (NI) is coupled to a memory via the bus, and receives a schedule to a Direct Memory Access (DMA) controller on the NI. The schedule indicates one or more timeslots reserved for transmission of deterministic data, and further indicates one or more available timeslots which are not reserved for transmission of deterministic data.
