Abstract: This asynchronous processor core comprises a loading unit for sequentially loading instruction lines, functional units for executing instructions and a decoder for decoding instruction lines loaded by the loading unit into instructions executable by the functional units. It comprises an execution control module configured as a two-state automaton: a sleep state (S1), wherein the asynchronous processor core awaits an interrupt control signal to execute an interrupt routine; an execution state (S2), wherein the decoder awaits a new interrupt routine instruction line to be decoded. The execution control module additionally manages a state variable (status) of the loading unit to selectively authorize or prevent, according to at least the value of this state variable (status), the loading of a new instruction line.

Abstract: The invention is directed a method for transferring at least one datum between a real-time task producing a datum and a real-time task consuming said datum. The method may include, in response to initiation of a transfer of a datum by a current instance of an initiating task: creating at least one DMA descriptor describing the DMA transfer expected for said datum; inserting DMA descriptors into a list of descriptors awaiting processing by a DMA controller, said DMA descriptors being inserted in a manner sorted based on a sorting criterion relating to a visibility date of the data and/or a temporal behavior of the tasks; processing the descriptors on the list of DMA descriptors by executing DMA requests; and executing the following instance of the initiating task based on termination of the processing a predefined set of DMA descriptors on the list of descriptors.

Abstract: A method for measuring, using a radar or sonar, the velocity with respect to the ground of a carrier moving parallel to the ground, includes the following steps: a) orienting the line of sight of the radar or sonar toward the ground; b) emitting a plurality of radar or sonar signals (P1-PN) that are directed toward the ground, and acquiring respective echo signals (E1-EN); c) processing the acquired echo signals so as to obtain, for one or more echo delay values, a corresponding Doppler spectrum; d) for the or at least one the echo delay value, determining a high cut-off frequency of the corresponding Doppler spectrum; and e) computing the velocity of the carrier with respect to the ground on the basis of the one or more high cut-off frequencies. A system allowing such a method to be implemented.
