Abstract: The invention relates to a Rho GTPase activator, such as namely the cytotoxic necrotizing factor 1 (CNF1), for use in preventing and/or treating infections by a pathogen in a patient in need thereof. The invention also relates to a Rho GTPase activator, such as CNF1, for use in preventing and/or treating pathologies associated with an infection by a pathogen in a patient in need thereof. For instance, the invention relates to a Rho GTPase activator for use in treating infections by bacteria in a patient in need thereof and also relates to a Rho GTPase activator for use in reducing or eliminating bacteremia in a patient in need thereof.

Abstract: A circuit for controlling a memory including at least two areas to which access cannot be had simultaneously, the circuit including first circuitry for storing a series of read and/or write instructions separately for each of the areas, and second circuitry for detecting that a first instruction intended for a first area is a predetermined instruction to be followed by a period during which the first area can receive no other instruction, and third circuitry for, during the period, providing instructions to another memory area.

Abstract: A circuit including a memory connected to be accessible from a bidirectional bus, an MPEG decoder connected to the bus to be able to read coded and decoded data in the memory, and having a decoded data output connected to the bus according to a first path to be able to read from the memory data of a first image, and a first image display circuit, an input of which is connected to the bus to read from the memory the data written by the decoder, which also includes a decimator circuit, connected between the output of the decoder and the bus according to a second path to be able to write into the memory data of a second image, and a second image display circuit connected to the bus to read from the memory the data written by the decimator circuit.

Abstract: A circuit includes a microprocessor, an MPEG decoder for decoding an image sequence, and a memory common to the microprocessor and to the decoder. The circuit also includes a circuit for evaluating a decoder delay, a control circuit for, if the decoder delay is greater than a predetermined level, granting the decoder a memory access priority, and otherwise, granting the microprocessor the memory access priority.

Abstract: A method of arbitration among a plurality of n units which seek access to a resource is regulated according to grants identified by means of an arbitration method, which compares between one another the priorities, generating, for each pair of the units comprising in general a unit x and a unit y with respective priorities Px and Py, a selection signal at a high level if the result of the operation Px>=Py is true. The method generates, for the pairs of the units, respective cross-request signals and generates the grant for the ith unit as a logical product of all the cross-request signals req_i_z with z ranging from 1 to n, excluding the case of z=i.
