Abstract: A scalable neural network accelerator may include a first circuit for selecting a sub array of an array of registers, wherein the sub array comprises LH rows of registers and LW columns of registers, and wherein LH and RH are integers. The accelerator may also include a register for storing a value that determines LH. In addition, the accelerator may include a first load circuit for loading data received from the memory bus into registers of the sub array.

Abstract: In one embodiment of a header-compression method, a 32-bit timestamp value is divided by a 16- or 8-bit stride value using a plurality of 16/8-bit division operations, each performed using a corresponding hardware instruction issued to an arithmetic logic unit (ALU) of the corresponding communication device, such as an access terminal or a base station of a communication system. When specialized 32/16-bit and/or 32/8-bit division-logic circuitry is not available in the ALU, embodiments of the header-compression method can advantageously be used to improve the speed and efficiency of timestamp compression in communication devices.

Abstract: A seamless power transfer apparatus comprising a solar grid and a utility power grid. The apparatus comprises a smart switch electrically connected to the solar grid and to the utility grid. The smart switch does not allow the solar grid to supply power to the utility power grid at any time.

Abstract: In one embodiment of a header-compression method, a timestamp value is divided by a stride value using a plurality of binary-shift operations corresponding to a Taylor expansion series of the reciprocal stride value in a base of ½. When the division-logic circuitry of an arithmetic logic unit in the corresponding communication device is not designed to handle operands that can accommodate the length of the timestamp and/or stride values, the header-compression method can advantageously be used to improve the speed and efficiency of timestamp compression in communication devices.

Abstract: In one embodiment, a method includes receiving a media signal associated with a session established based on a session request. The session request is defined at a session exchange device associated with a media over internet protocol (MoIP) network. The method also includes sending a portion of the media signal to a dual-tone multi-frequency (DTMF) analysis module during a sampling time period after a non-sampling time period.

Abstract: In one embodiment, a method includes receiving a first internet protocol (IP) packet having information associated with a dual-tone multi-frequency (DTMF) signal. The information of the first IP packet is configured based on a protocol associated with a first layer of a media over internet protocol (MoIP) network. The first IP packet is associated with a destination endpoint. The method also includes producing a second IP packet having information associated with the DTMF signal. The information of the second IP packet is configured based on a protocol associated with a second layer of the MoIP network and a DTMF conversion policy associated with the destination endpoint. The second layer is different than the first layer.
