  • Patent number: 10361890
    Abstract: A method can be used for transmission of at least one packet of at least one bit over a serial link capable of taking two different states respectively associated with the two possible logical values of the at least one transmitted bit. Starting from a transmission start time of the at least one bit and up to the expiration of a first portion of a bit time associated with the at least one bit, the link is placed in one of its states depending on the logical value of the at least one bit. Upon the expiration of the first portion of this bit time, a first additional transition is generated over the link so as to place the link in its other state up to the expiration of the bit time.

  • Patent number: 10306248
    Abstract: A method and device for real-time generation of a multiresolution representation of a digital image for real-time generation are disclosed. A sequence of main representations of the digital image is stored at successive different main resolutions in a main memory. A part of a current main representation is loaded from the main memory into a local memory via a bus. A current main representation is processed by determining a corresponding part of an intermediate representation of the image having an intermediate resolution lying between the resolution of the current main representation and the resolution of the subsequent main representation. The loading and processing steps are repeated for other parts of the current main representation until all parts of the current main representation have been successively loaded and processed.
