  • Publication number: 20150186311
    Abstract: Disclosed herein is a memory access controller. The memory access controller includes an event detection unit (EDU) to receive an indication that a trigger event has been detected in an electronic component, wherein the EDU is to select a memory access context based on the trigger event. The memory access controller includes an event selector to start a DMA operation based on the memory context.

  • Patent number: 7849255
    Abstract: A memory comprises at least one array of memory elements, a partition of the at least one array into a plurality of sub-arrays of the memory elements, and an array configuration circuit for selectively putting the at least one array in one of two operating configurations. In a first operating configuration, the memory elements of the at least one array are coupled one to another to form a monodimensional sequentially-accessible memory, while in a second operating configuration the memory elements in each sub-array are coupled to one another so as to form an independent monodimensional sequentially-accessible memory block, a data content of any memory element of the sub-array being rotatable by shifts through the memory elements of the sub-array. A sub-array selector, responsive to a first memory address, selects one among the at least two sub-arrays according to the first memory address, and enables access to the selected sub-array.

  • Patent number: 7649990
    Abstract: An apparatus arranged to accept digital data as an input and to process the data according to one of either the Secure Hash Algorithm (SHA-1) or Message Digest (MD5) algorithm to produce a fixed length output word. The apparatus includes a plurality of rotational registers for storing data, one of the registers arranged to receive the input data, and data stores for initialization of some of the plurality of registers according to whether the SHA-1 or MD5 algorithm is used. The data stores include fixed data relating to SHA-1 and MD5 operation. Also included is a plurality of dedicated combinatorial logic circuits arranged to perform logic operations on data stored in selected ones of the plurality of registers.
