Broadcom Corporation is an American fabless semiconductor company in the wireless and broadband communication business. The company is headquartered in Irvine, California. Broadcom was founded by a professor-student pair Henry Samueli and Henry T. Nicholas III from the University of California, Los Angeles in 1991. In 1995, the company moved from its Westwood, Los Angeles, office to Irvine, California. In 1998, Broadcom became a public company on the NASDAQ exchange and now employs approximately 11,750 people worldwide in more than 15 countries.Broadcom is among Gartner's Top 10 Semiconductor Vendors by revenue. In 2012, Broadcom's total revenue was $8.01 billion. In 2013, Broadcom was No. 327 on the Fortune 500, climbing 17 places from its 2012 ranking of No. 344. Broadcom first landed on the Fortune 500 in 2009. Wikipedia.

A network gateway in a vehicle connects heterogeneous networks and buses within the vehicle. The gateway implements hardware acceleration to accomplish protocol translation, e.g., between CAN, LIN, Flexray, and Ethernet buses and networks. In particular, the gateway provides hardware accelerated packet filtering, header lookup, and packet aggregation features.

A stream at a source device may be transmitted over multiple channels. At the input of the channels that packets from the stream may be grouped into chunks. Informational packets may be appended to the chunks. The informational packets may include sequencing information for the chunks and packet-to-packet timing information. The chunks may then be distributed over the multiple channels. After transmission over the channels, the informational packets may be extracted from the chunks. Reconstruction circuitry, at the destination device, may determine the sequence of the chunks at the source device based on the sequencing information. The reconstruction circuitry may also determine relative timings of the packets within the single stream based on the packet-to-packet timing information. The packets may be released from buffers in accord with the determined packet-to-packet timing information and the sequencing information to recreate the relative timings within the single stream at the destination device.

A video decoder or encoder can be used to convert and process different video streams having different combinations of frame rate and Chroma fidelity. Rather than setting the maximum sample rate of the encoder based on a Luma sample rate, the encoders throughput is set based on a maximum color sample rate. Additionally, the picture buffer size can be set based on a maximum number of color pictures. An input of the video decoder receives an input video stream having a given display resolution and encoded in a first format employing a first combination of frame rate and Chroma fidelity. Processing circuitry in the decoder converts the input video stream from the first format to an output video stream having a second format, the second format having the given display resolution and employing a second combination of frame rate and Chroma fidelity different from the first combination.

A device implementing an adaptive positioning system may include at least one processor that is configured to concurrently implement a first positioning system that generates first positioning information items and a second positioning system that generates second positioning information items. The processor may be configured to buffer the second positioning information items generated by the second positioning system and to determine a position estimation for the device based on the first positioning information items generated by the first positioning system. The processor may be configured to detect a degradation in a quality of the first positioning system. The processor may be configured to, in response to detecting the degradation in the quality of the first positioning system, determine the position estimation for the device based at least in part on at least one of the buffered second positioning information items generated by the second positioning system.

Memory devices, such as MRAM devices, are described that comprise memory elements for storing data and configuration logic for programming memory elements using a two phase boost. The memory devices perform the two phase boosting to program anti-parallel data values during a first programming phase and to program parallel data values during a second programming phase that is subsequent to the first programming phase. The voltage boost is provided by a high percentage of memory elements in a memory device by simultaneously transitioning the source line of the memory elements from a reference voltage to a source voltage during the first programming phase to effectively double the activation voltage for gates of transistors in the memory elements to program anti-parallel data values. Methods are also described for programming memory elements using a two phase boost.

A system and method that provide reduced latency in a video signal processing system. Various aspects of the present invention may comprise receiving a current request from a user for first video information. Such a request may, for example, be received with a user interface module. A first video stream and a second video stream may be received simultaneously, where the first video stream comprises the first video information currently requested by the user, and the second video stream comprises second video information not currently requested by the user. A video receiver module may, for example, perform such receiving. The first video stream may be processed to present the first video information to the user at the current time. Further, the second video stream may be pre-processed in preparation for being presented to the user in the future. A video processing module may, for example, perform such video stream processing.

A wireless communication device (alternatively, device, WDEV, etc.) includes a processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. A WDEV generates and transmits an OFDM packet that specifies resource allocation of a communication channel for other WDEVs. The WDEV then support communications with the other WDEVs based on the resource allocation of the communication channel. The OFDM packet includes an OFDMA indicator bit and a multi-purpose field that serves different purposes based on setting of the OFDMA indicator bit (e.g., the multi-purpose field is used for different purposes when the OFDMA indicator bit indicates OFDMA or non-OFDMA resource allocation).

Methods, systems, and apparatuses are described for determining relative locations of wireless loudspeakers and performing channel mapping thereof n audio processing component utilizes sounds produced by wireless loudspeakers during setup/installation procedures, which are received by a microphone at locations in an acoustic space, to determine an amount of time between when the audio signal is initially transmitted and when the microphone signal is received. The audio processing component also utilizes wireless timing signals provided by a wireless transceiver, at locations in the acoustic space, to wireless loudspeakers and then back to the wireless transceiver to determine an amount of time between transmission and reception by the wireless transceiver. The timing delays are used to determine the locations of the wireless loudspeakers in the acoustic space. Based on the determined locations, the audio processing component generates indications of correct or incorrect wireless loudspeaker placements, and performs audio channel mapping.
