Methods and apparatus are provided for semiconductor devices. In particular, the present invention relates to techniques which seek to improve the throughput of data in multi-hop communication systems. The N wireless transmitting devices transmit frames to the respective N wireless receiving devices by a wireless carrier. Work stealing double-ended queues, where contention is reduced, are described to provide dynamic load balancing among the threads. To aid in detecting the sync sequence, the two sync bits are rotated each cell cycle.
