  • Stand-by mode of an electronic circuit
    Patent number: 10719331
    Abstract: A microcontroller includes a core and a unit for managing the power supply of the core that includes an input for receiving an external signal indicating a leaving of a stand-by mode of operation. A signal intercepting unit intercepts the external signal and transmitting it with a delay to the unit for managing.
    Type: Grant

  • System for automatically generating optimized codes
    Patent number: 7979852
    Abstract: The inventive system for automatically generating optimizes codes (19) which are operational on a predefined hardware platform (90) comprises at least one processor which is (91) based on code sources (17) provided by users and comprises means (51, 52) for receiving symbolic code sequences or standard sequences (1) representative for the processor (91) behavior in terms of performance for a predetermined application area, means (53), for receiving static parameters (2), means (55) for receiving dynamic parameters (7), an analysing device (10) for defining optimization rules (9) on the basis of performance tests and measures determined on the basis of the standard sequences (1) and the static (2) and dynamic (7) parameters, a device (80) for optimizing and generating the code receiving the standard sequences (1) and the optimization rules (9) for examining the code sources (17) of the users, detecting optimizable loops, decomposing into cores and for assembling and injecting the codes in such a way that the op
