    摘要: Systems and methods for providing efficient memory allocation, reduced processor intervention and power consumption, and increased memory access bandwidth. One embodiment comprises a system including a plurality of memory units which are accessible in parallel, a dynamic memory unit configured to dynamically allocate and deallocate storage space in the memory units, and a plurality of direct memory access (DMA) engines configured to access the memory units in parallel through the memory management subsystem. The system may be implemented in the MAC engine of a device that communicates with other devices via a wireless communication link. This embodiment may store packets in FIFOs within the memory units as elements of linked list data structures that can be joined together without having to move the previously stored data. DMA engines access a context table to obtain DMA channel information that enables them to move data through appropriate DMA channels.

    摘要: Methods, systems, and apparatuses are described which are capable of mitigating interference between piconets. Devices on a piconet may detect a certain degree of interference. When this interference is deemed as arising from another piconet, the first piconet may cease transmitting on a set of bands while the interfering piconet may continue to transmit on this set of bands. Furthermore, the interfering piconet may cease transmitting on another orthogonal set of bands within the frequency spectrum while the original piconet continues to utilize these bands. Transmission on these sets of bands may be resumed after a predetermined time period. In this manner interference between the two piconets may be minimized.
