    摘要: A method for constituting a look-up table of logic addresses and physical addresses of blocks of a memory is provided. The memory saving for each block a state of the block, and for each used block the logic address of the block, the method involving: reading the state of each block in the memory, storing the physical address of each block in the used state in an address field of a line selected in the table from the logic address of the block read in the memory, for each block in the free state in the memory, storing the physical address of the block, while marking a line of the table, selected from the physical address of the block, and storing an address corresponding to each marked line of the table, in a free address field of the table.

    摘要: In an embodiment an electronic device includes a first electronic circuit having a capacitive element with a variable capacitance, wherein the first electronic circuit is configured to couple the capacitive element to an antenna, to measure, by successive iterations, a first analog signal representative of a variation of an instantaneous electric power received by the antenna or representative of the instantaneous electric power received by the antenna and to modify the capacitance of the capacitive element until an amplitude of the instantaneous electric power received by the antenna is a maximum, wherein the antenna is configured to capture an amplitude-modulated electromagnetic field.

    摘要: An embodiment method for estimating a missing or incorrect value in a table of values generated by a photosite matrix comprises a definition of a zone of the table comprising the value to be estimated and other values, referred to as neighboring values, and an estimation of the value to be estimated based on the primary neighboring values and the weight associated with these primary neighboring values, wherein a weight of each neighboring value, referred to as primary neighboring value, of the same colorimetric component as that of the missing or incorrect value to be estimated, is determined according to differences between neighboring values disposed on an axis and neighboring values disposed parallel with this axis and positioned in relation to this axis on the same side as the primary neighboring value for which the weight is determined.

    摘要: In an embodiment a device includes a first circuit and a second circuit, wherein the first circuit is configured to generate a fourth signal and a fifth signal by applying the phase shift respectively to a first signal and to a second signal and deliver a sixth signal corresponding to a sampling over one bit of the fourth signal, a seventh signal corresponding to a sampling over one bit of the fifth signal, an eighth signal corresponding to a sampling over one bit of a difference between the fourth and fifth signals, and a ninth signal corresponding to a sampling over one bit of a sum between the fourth and fifth signals, wherein the second circuit is configured to receive the sixth, seventh, eighth, and ninth signals and determine, during a first phase where the first and second signals are representative of a first known symbol of a QPSK constellation, a state of a first bit from among a first state and a second state based on the eighth and ninth signals.
