  • Patent number: 7835401
    Abstract: A system and method are provided for framing messages in a data streams encoded with redundant information for transmission and recovering the messages at a receiver. The transmission method accepts an energy waveform representing N words at a first bit rate, encoded with redundant information, where each word includes P number of bits. The N words are transformed, creating N transcoded words, where each transcoded word includes Q number of bits, and where Q<P. The N transcoded words are mapped into M lanes in a buffer memory, where M>1 and each lane receives a frame of N/M transcoded words. A frame alignment marker is generated and mapped into each frame. Each frame is represented as an energy waveform that is transmitted on a corresponding physical lane at the first bit rate divided by M.

  • Patent number: 7836199
    Abstract: A system and method are provided for negotiating a link data rate in a communication system using a plurality of data rates. In a system including a first device network-connected to a second device, auto-negotiation (AN) messages are mutually transmitted. The AN messages indicate rate information such as preferred data rate capabilities, if the device has a dual-rate capability, single data rate capabilities, or is capable of communicating over a plurality of physical medium lanes. If the AN messages are mutually transmitted, a negotiated link data rate is established. However, if one of the devices cannot send AN messages, the other device times-out, and a link data rate is established at the data rate transmitted by the device that is not AN-capable.

  • Patent number: 7835393
    Abstract: A system and method are provided for converting multichannel serial data streams into packets. The method accepts a plurality of serial data streams in a corresponding plurality of channels. In a time domain multiplexed (TDM) fashion, groups with an undetermined number of data bits are packed from each data stream, into an associated channel segment queue, where each segment includes a predetermined number of bits. In a TDM fashion, segments are loaded into an associated channel payload queue, where each payload includes a predetermined number of segments. Once a payload is filled, an associated pointer is created in a pointer queue. The method selects a pointer from the pointer queue, creates a packet from the payload associated with the selected pointer, and transmits the packet via a packet interface. The packet overhead may include information stored in the pointer, a packet header, or a cyclic redundancy check (CRC) checksum.

  • Patent number: 7826563
    Abstract: A system and method are provided for multi-modulus division. The method accepts an input first signal having a first frequency and divides the first frequency by an integral number. A second signal is generated with a plurality of phase outputs, each having a second frequency. Using a daisy-chain register controller, phase outputs are selected and supplied as a third signal with a frequency. Selecting phase outputs using the daisy-chain register controller includes supplying the third signal as a clock signal to registers having outputs connected in a daisy-chain. Then, a sequence of register output pulses is generated in response to the clock signals, and register output pulses are chosen from the sequence to select second signal phase outputs. By using 8-second signal phase outputs, a third signal is obtained with a frequency equal to the second frequency multiplied by one of the following numbers: 0.75, 0.875, 1, 1.125, or 1.25.

  • Patent number: 7826490
    Abstract: A system and method are provided for mapping information into Synchronous Payload Envelopes (SPEs). The method provides information bytes at a nominal system clock-based data rate, which is about equal to a system clock, but may be adjusted. An external clock has a rate approximately equal to the system clock rate. The method generates SPEs with identically-positioned information bytes, regardless of differences between the system and external clock rates. The SPEs are combined with Transport Overhead (TOH) and transmitted as a message frame at the external clock rate. SPEs are generated maintaining the positions of the information bytes within each SPE, without pointer adjustments, despite differences between the system and external clock rates. Expressed another way, message frames are generated with payload and TOH sections, and the information bytes are located exclusively in the payload sections. As a result, constant pointer values (e.g., H1/H2 or V1/V2) are maintained for all the SPEs.

  • Patent number: 7807225
    Abstract: A high-density plasma method is provided for forming a SiOXNY thin-film. The method provides a substrate and introduces a silicon (Si) precursor. A thin-film is deposited overlying the substrate, using a high density (HD) plasma-enhanced chemical vapor deposition (PECVD) process. As a result, a SiOXNY thin-film is formed, where (X+Y<2 and Y>0). The SiOXNY thin-film can be stoichiometric or non-stoichiometric. The SiOXNY thin-film can be graded, meaning the values of X and Y vary with the thickness of the SiOXNY thin-film. Further, the process enables the in-situ deposition of a SiOXNY thin-film multilayer structure, where the different layers may be stoichiometric, non-stoichiometric, graded, and combinations of the above-mentioned types of SiOXNY thin-films.

  • Patent number: 7774522
    Abstract: A system and method have been provided for pushing cacheable control messages to a processor. The method accepts a first control message, identified as cacheable and addressed to a processor, from a peripheral device. The first control message is allocated into a cache that is associated with the processor, but not associated with the peripheral device. In response to a read-prompt the processor reads the first control message directly from the cache. The read-prompt can be a hardware interrupt generated by the peripheral device referencing the first control message. For example, the peripheral may determine that the first control message has been allocated into the cache and generate a hardware interrupt associated with the first control message. Then, the processor reads the first control message in response to the hardware interrupt read-prompt. Alternately, the read-prompt can be the processor polling the cache for pending control messages.
