    Abstract: A method of storing a picture in a memory such that bandwidth can be reduced when retrieving an array portion of the picture from the memory, and a memory architecture are disclosed. The memory is subdivided into a plurality of words for storing a picture having rows and columns. The picture is partitioned into two or more stripes each having a predetermined number of columns. The number of bytes in one row of one stripe is equal to the number of bytes in one word, for storing the data in one row of a stripe in one word.

    Abstract translation: 一种将图像存储在存储器中的方法,使得可以在从存储器检索图像的阵列部分时减少带宽,并且公开了存储器架构。 存储器被细分为用于存储具有行和列的图片的多个单词。 将图像分割成两条或多条,每条具有预定数量的列。 一个条带的一行中的字节数等于一个字中的字节数,用于以一个字存储数据的一行。

    Abstract: The invention concerns Circuitry for encrypting at least a part of an input data (Bi) flow and generating a tag based on said input data flow with a same ciphering algorithm and a same key (K), said algorithm comprising iterative computations by at least two operation units, said circuitry comprising a pipeline comprising: an input selection unit (612) arranged to receive first data values to generate encryption sequences with said ciphering algorithm, second data values to generate temporary tags with said ciphering algorithm and an output of the pipeline; a first stage (627) arranged to receive an output of said input selection unit and comprising at least a first operation unit (632); and a second stage (635) arranged to receive an output of the first stage, comprising at least a second operation unit (648) and providing said output of the pipeline.
