摘要： A method of low latency encoding of an input bit sequence (S0) to yield an encoded bit sequence (S), and a corresponding decoding method, said encoding method including: a first encoding step (E1) applied to bits of the input bit sequence (S0), using a first code; an interleaving step (E3) in which an interleaver interleaves the bits obtained from said first code; and a parity, second encoding step (E4) applied to the bits obtained from said interleaver, using a second code, to generate said encoded bit sequence (S). The parity, second encoding step (E4) starts after a predetermined number Δ of bits have been interleaved, said predetermined number Δ of bits ranging between a first lower number Δi of bits depending on one or more parameters of said interleaving step (E3) and a first higher number Δs of bits corresponding to the total number of bits to be processed during said interleaving step (E3).

摘要： The invention relates to correcting codes for encoding and decoding a data signal. A signal including data variables is coded into a signal including the data variables and parity variables. The encoding and decoding operations are based on a parity check matrix comprised of a systematic matrix and a parity matrix and having rows corresponding coefficients of parity equations and distributed into decoding windows of same size. In order to increase convergence of the iterative decoding, the elements of at least one column of the systematic matrix associated with a decoding window are “0s”, except for a single element which is a “1”. A data variable is only involved in one equation of the window and not involved in solving the equations of other windows as long as the solving of equations of the window is not achieved.

摘要： The device and method disclosed relate to the field of electronic devices and methods enabling the transposition of any even-order square matrix, the elements of which are given in sequence. The goal is to provide for the transposition of sequences of data representing elementary image blocks, without any duplication of the memory space needed to store an elementary block, in optimizing the two parameters of operating speed and space occupied on silicon. This goal is achieved by a buffer memory divided into two identical storage half-planes, working together with a device for the sequencing of the reading/writing operations, providing simultaneously for a reading operation on one of the storage half-planes and a writing operation on the other half-plane.

摘要： A random access memory (RAM) comprises memory cells each including an RS type flip-flop having complementary data inputs and transistors for forcing the flip-flop by that one of two data wires which is at a given level (high level for example) when a selection wire is at a first given level (high level for example). The flip-flop is connected to an output wire by circuitry for maintaining the output wire at the high level as long as the selection wire is at the first level and for causing the output wire to take the level corresponding to the condition of the flip-flop when the selection wire is brought to the other level. The transistors are preferably N-MOS for higher speed.
