Abstract: A method for controlling a low-power state of a pair of serial interfaces using a pair of flow-control signal lines may include enabling a first of the flow-control lines by a first one of the interfaces for signaling a transmission request to the second interface. The method may also include, in response to the transmission request, waking up to a live state from a low-power state and enabling a second flow-control line for signaling a transmission authorization to the first interface. In response to the transmission authorization, the method may include initiating a transmission of a message to the second interface, and upon reaching an offset before the end of the message transmission, disabling the first flow-control line by the first interface. The method may also include, at the end of the message transmission, disabling the second flow-control line and going back into the low-power state.

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.

Abstract: A virtual memory is partitioned into virtual partitions, each partition being subdivided into virtual sub-partitions and each sub-partition corresponding to a combination of multiple sectors of identical or different sizes of a physical memory. When an allocation request is made for a virtual memory space having a given memory size, a free partition is selected, a virtual sub-partition is selected corresponding to a combination of sectors having a minimum total size covering the given memory size of the virtual memory to be allocated, and free sectors of the physical memory are selected corresponding to the selected combination. A determination is made of a correspondence table between the selected virtual partition and the initial physical addresses of the selected free sectors, and a virtual address is generated.
