Abstract: A storage device stores data in groups of memory cells using vectors corresponding to voltage code codewords, each codeword having k entries. Entries have values selected from a set of at least three entry values and 2n distinct inputs can be encoded into k-entry codewords for some n>k. A vector storage element comprising k cells can store an k electrical quantities (voltage, current, etc.) corresponding to a codeword. The voltage code is such that, for at least one position of a vector, there are at least three vectors having distinct entry values at that position and, for at least a subset of the possible codewords, the sum of the entry values over the positions of each vector is constant from vector to vector in that subset. The storage device might be an integrated circuit device, a discrete memory device, or a device having embedded memory.

Also local deserializers serially receive first n-bit codes, respectively, from remote serializers, respectively. One of the first n-bit codes transmitted to one of the remote serializers indicates one of the local deserializers is not link aligned.

Abstract: Instructions and logic provide SIMD address conflict resolution with vector population count functionality. Some embodiments include processors with a register with a variable plurality of data fields, each of the data fields to store a variable second plurality of bits. A destination register has corresponding data fields, each of these data fields to store a count of the number of bits set to one for corresponding data fields. Responsive to decoding a vector population count instruction, execution units count the number of bits set to one for each of data fields in the register, and store the counts in corresponding data fields of the first destination register. Vector population count instructions can be used with variable sized elements and conflict masks to generate iteration counts and completion masks to be used each iteration to resolve dependencies in gather-modify-scatter SIMD operations.

Abstract: An encoder encodes data into a series of parallel codewords. Each codeword is expressed two sets of logic values (e.g., a set of logic 0s and a set of logic 1s) on output nodes. The encoder selects a current codeword from a group of codewords in a codespace which does not overlap the other group of codewords, i.e., codewords in a given group of codewords are not included in any other group of codewords in the codespace. This property allows a receiver of the codewords to be simplified. In particular, a mathematical operation performed on symbols in the current codeword uniquely specifies the corresponding group of codewords. This allows a decoder to decode the current codeword using comparisons of symbols received on a subset of all possible combinations of node pairs.

Abstract translation: 编码器将数据编码成一系列并行码字。 每个码字在输出节点上被表示为两组逻辑值（例如，一组逻辑0和一组逻辑1）。 编码器在代码空间中从不与另一组码字重叠的码字组中选择当前码字，即，给定码字组中的码字不包括在码空间中任何其他码字组中。 该属性允许简化码字的接收者。 特别地，对当前码字中的符号执行的数学运算唯一地指定相应的码字组。 这允许解码器使用在节点对的所有可能组合的子集上接收的符号的比较来解码当前码字。

Abstract: During decoding and encoding, the starting disparity of a current block is computed by using a disparity at some previous reference point and disparity characteristics of bytes from the reference point to a current block boundary. The characteristics of the bytes are whether the bytes are unbalanced coded vectors and whether the number of unbalanced vectors is even or odd. Alternately, the characteristics of the bytes are whether the bytes are balanced and how many balanced coded vectors exist. New classifications are created for encoding and decoding 3B/4B and 5B/6B transmission codes. Separate functions are created that address specifically disparity aspects. A dispartiy violation at the front of a byte is detected during decoding by comparing a required front-end disparity of the byte with the actual running disparity by assuming the actual running disparity is equivalent to an exit disparity of the next preceding byte that is disparity dependent.

Abstract translation: 在解码和编码期间，通过使用某些先前参考点的视差和从参考点到当前块边界的字节的差异特性来计算当前块的起始视差。 字节的特征是字节是不平衡编码矢量，以及不平衡矢量的数量是偶数还是奇数。 或者，字节的特性是字节是否平衡，并且存在多少个平衡编码矢量。 创建新的分类用于编码和解码3B / 4B和5B / 6B传输码。 创建独立的功能来解决特定的差异方面。 通过将字节的所需前端视差与实际运行差异进行比较，假设实际的运行差异等于下一个先前字节的出现差异，这是视差依赖的，在解码期间检测到一个字节前方的违规行为 。
