Abstract: The present disclosure describes techniques and apparatuses for a hardware-implemented Adelson-Velskii and Landis' (AVL) tree module. In some aspects, commands are received at the AVL tree module that request operations be performed for an AVL tree table stored in memory. Each command is written to one of multiple hardware threads of the AVL tree module that perform AVL tree operations by causing records of the AVL tree table to be read from memory using a single read operation and then written to the AVL tree module, modifying those records without accessing memory, and causing modified records to be written back to memory using a single write operation. Once a command is written to a hardware thread, the hardware thread can perform the corresponding AVL tree operation. After the AVL tree operation is performed, results are returned to the requesting agent to indicate whether the AVL tree operation was performed successfully.

Abstract: An integrated circuit includes a generator. The generator, based on a summation signal, generates a clock signal having a frequency. Multiple devices generate respective requests. Each of the requests requests transfer of data on a bus. Each of the devices is configured to, based on the frequency of the clock signal, transfer the data for the corresponding request on the bus. A summer receives the requests and based on a number of the requests being in an asserted state during a first period of time, generates the summation signal. A first module, based on the summation signal, increases a second period of time that a first request is in an asserted state. The second period of time is increased to include or overlap the first period of time. The summer, as a result of the increase, generates the summation signal further based on the first request.

Abstract: A wireless network bridge controls a first network interface to operate as a first station in a first wireless network, and controls a second network interface to operate as an access point in a second wireless network. The bridge controls a bridge table that includes an entry associating one or more network addresses of a second station with the second network interface. The second station is accessible through the second network interface operating as an access point. The bridge receives a packet for communication between the second station and a network device in the first wireless network; examines the packet to find one or more network addresses included in the packet; associates the packet with the second station by performing a lookup of the bridge table; and communicates packet information with the second station through the second network interface, and with the network device through the first network interface.

Abstract: A first network interface and a second network interface of a wireless network device are respectively controlled to operate as a station in a first wireless network and as an access point in a second wireless network. A beacon message, which includes a first signal strength of a first bridge node that is an access point in the first wireless network, is transmitted through the second network interface. A probe response message, which includes a second signal strength of a second bridge node that is an access point in a third wireless network, is received at the second network interface. Conditioned on determining that the second signal strength is greater than the first signal strength, the first network interface is disconnected from the first bridge node and is connected to the second bridge node to operate as a station in the third wireless network.
