Tality released a high-performance medium access controller (MAC) for IEE 802.11 wireless local area network baseband chips. It consists of a synthesizable MAC core and protocol stack. The core is available in three configurations: a dual-mode IEEE 802.11a/b design using two ARM7TDMI processors; a similar design using a single ARM9 processor; and an IEEE 802.11b (Wi-Fi) design using a single ARM7TDMI. The core and protocol stack were co-developed as an optimized and integrated system. The modular architecture enables rapid modification to conform to evolutions in the IEEE 802.11 specification. The system is designed for maximum data throughput with minimum processor load and chip power consumption. The MAC executes all datapath functions, leaving the host processor to manage and control the protocol at an abstracted level. The IEEE 802.11a/b MAC core and its pre-designed baseband configurations are available now for integration into chip designs.
