  • Publication number: 20140075258
    Abstract: A method includes receiving a signal, which carries data that is encoded with an Error Correction Code (ECC), and correcting the received signal with an adaptive receiver loop. Soft input metrics for the data are computed over the corrected signal. The ECC is decoded using a decoder, which estimates soft output metrics based on the soft input metrics, by operating the decoder in an alternating pattern of external iterations that update one or more of the soft input metrics based on one or more of the soft output metrics, and internal iterations that update the soft output metrics but not the soft input metrics. The adaptive receiver loop is adjusted in a schedule that is defined relative to the pattern of the external and the internal iterations of the decoder.

    Abstract: A transmitting and receiving system includes first and second transmitting and receiving apparatuses. The first transmitting and receiving apparatus includes a generating unit and a transmitting unit. The generating unit generates a packet for transmission by attaching packet identification information to transmission data to which an error detection code is attached, and uses, as the packet identification information, a code that is capable of detecting a 1-bit error caused by transmission of the packet for transmission. The transmitting unit converts the number of bits of the packet for transmission and transmits the converted packet. The second transmitting and receiving apparatus includes a receiving unit and a correcting unit. The receiving unit subjects the transmitted packet to inverse conversion of the number of bits. The correcting unit detects a 1-bit error in the packet identification information of the inverse-converted packet, and corrects the error.

    Abstract: The recovery of data during programming, such as in the case of a broken word-line, is considered. The arrangement described assumes that k pages may be corrupted when the system finishes programming a block. Then these corrupted pages can be recovered using an erasure code. In order to recover any k pages, the system will compute and temporarily store k parity pages in the controller. These k parity pages may be computed on-the-fly as the data pages are received from the host. Once programming of the block is finished, a post-write read may be done in order to validate that the data is stored reliably. If no problem is detected during EPWR, then the parity pages in the controller may be discarded. In case a problem is detected, and data in up to k pages is corrupt on some bad word-lines, then the missing data is recovered using the k parity pages that are stored in the controller and using the other non-corrupted pages that are read from the block of the memory array and decoded.

  • Publication number: 20120254653
    Abstract: A method and system for performing chaincast communication to multiple communication systems within a system of coupled electronic devices. In one implementation the electronic devices can be computer systems and the system of coupled electronic devices includes the Internet. The present invention provides a system wherein a broadcast source communicates broadcast information (e.g., encoded audio radio content, encoded audio/video television content, program instructions, etc.) to a first group of electronic devices. The first group of electronic devices can be instructed by a transmission scheduler to then communicate (e.g., forward) the broadcast information to other electronic devices which devices can also be instructed to communicate to more devices, etc., thereby reducing the bandwidth requirements of the communication channel between the broadcast source and the first group of electronic devices.

  • Publication number: 20120240010
    Abstract: A controller includes a link interface that is to couple to a first link to communicate bi-directional data and a second link to transmit unidirectional error-detection information. An encoder is to dynamically add first error-detection information to at least a portion of write data. A transmitter, coupled to the link interface, is to transmit the write data. A delay element is coupled to an output from the encoder. A receiver, coupled to the link interface, is to receive second error-detection information corresponding to at least the portion of the write data. Error-detection logic is coupled to an output from the delay element and an output from the receiver. The error-detection logic is to determine errors in at least the portion of the write data by comparing the first error-detection information and the second error-detection information, and, if an error is detected, is to assert an error condition.

  • Publication number: 20120221925
    Abstract: A data recovery method includes the following steps. Firstly, plural sampling values are classified into a first group, a second group, a third group and a fourth group. A first channel estimation value and a second channel estimation value are generated according to the sampling values of the second group and the third group. A judging step is performed to judge whether a first sampling value of the first group is lower than the first channel estimation value or a second sampling value of the fourth group is higher than the second channel estimation value. If the judging condition is satisfied, a polarity of the first sampling value or the second sampling value is changed and then the plural sampling values are outputted. If the judging condition is not satisfied, the plural sampling values are directly outputted.

    Abstract: A machine-actionable memory comprises one or more machine-actionable records arranged according to a data structure. Such a data structure may include links that respectively map between: a RID field, the contents of which denote an identification (ID) of a remediation (RID); at least one TID field, the contents of which denotes an ID of at least two technologies (TIDs), respectively; and at least one ACTID field, the contents of which denotes an ID of an action (ACTID). A method, of selecting a remediation that is appropriate to a technology present on a machine to be remediated, may include: providing such a machine-actionable memory; and indexing into the memory using a given RID value and a given TID value to determine values of the at-least-one ACTID corresponding to the given RID value and appropriate to the given TID value.

  • Publication number: 20120166904
    Abstract: In a memory system, a spare error correction bit is produced by processing data to be stored in sufficiently large chunks that the number of error correction bits required to protect each chunk are fewer than the available error correction signal lines on a memory bus and storage device. The spare bit is then used for an inversion bit in a parallel data bus inversion scheme, wherein data is selectively inverted to minimize bus switching. The transmission of data and error correction bits are spread over multiple phases, wherein parallel data bus inversion is applied to each phase. Alternatively, the transmission of data and error correction bits may be transmitted and stored in a single transaction. In either case, the spare bit is transmitted on a conventional memory bus and stored in a conventional memory module along with data and error correction bits.

    Abstract: Supporting distributed key-based processes is described. In an embodiment, servers at a data center provide a key-based process for carrying out computationally expensive tasks and are connected using point to point connections in a geometric topology such as a torus. In an example, aggregation trees are built on top of the geometric topology of the data center, each aggregation tree being a sequence of servers in the data center that forms a tree structure. In an embodiment packets of data are sent from the leaves of the trees to the root and at each server along the tree the packets are aggregated using a combiner function of the key-based process. In an embodiment, if a server fails, the trees are dynamically recomputed and a recovery phase is triggered to resend any packets lost at the failed server. In some embodiments, packets are scheduled by inspecting the content of the packets.
