20110158264 | LOW-JITTER END-TO-END LATENCY CONTROL SCHEME FOR ISOCHRONOUS COMMUNICATIONS BASED ON TRANSMITTER TIMESTAMP INFORMATION - A latency control mechanism for a communication system provides a known constant end-to-end delay between an audio source and one or more end node destinations, even in the case where different paths are used to reach the end nodes. A very low jitter time on the end-to-end latency is obtained, and the latency is controllable within a given range in dependence on the constraints imposed by the implementation. A block RX DPLL and latency control unit adjusts the reading moment and position from the RX buffer so that a delay between the time stamp taken at the source side by the transmitter time stamp unit, and the time stamp taken at the receiver side by receiver time stamp unit is constant and equal to a given value. | 06-30-2011 |
20120033620 | SYNCHRONIZATION FOR DATA TRANSFERS BETWEEN PHYSICAL LAYERS - Various embodiments relate to a system and related method that enable transfer of control and data messages in a wireless communication network between devices operating on different physical layers (PHY). Control data and/or isochronous data and/or asynchronous data may be transferred between devices that operate on different physical layers through a bridging device, while minimizing latency and buffering. The bridging device may contain interfaces that may operate on each of the respective physical layers. A first interface may receive a first superframe from a device in a first physical layer (PHY | 02-09-2012 |
20140043864 | POWER SUPPLY CIRCUIT USING DC/DC CONVERTER - A power supply circuit comprises an input for receiving a power supply from a battery and a DC/DC converter for supplying a converted voltage to a load. A regulator is used for controlling the DC/DC converter such that the current drawn from the converter is smoothed. A charge storage device at the output of the DC/DC converter enables delivery of a non-constant current to the load. | 02-13-2014 |

20160132391 | SLEEP MODE OPERATION FOR VOLATILE MEMORY CIRCUITS - Aspects of the present disclosure are directed to circuits, apparatuses and methods for operating volatile memory circuits. According to an example embodiment, an apparatus includes a volatile memory circuit and a control circuit coupled to the volatile memory circuit. The control circuit is configured to generate and store parity data for data blocks written to the volatile memory circuit. The control circuit places the volatile memory circuit in a sleep mode in response to a first control signal. In response to a second control signal, the control circuit places the volatile memory into an active mode. In further response to the second control signal the control circuit detects and corrects errors in the data blocks stored in the volatile memory using the stored parity data. | 05-12-2016 |
