The present disclosure relates to a method for enabling a virtual processing unit to access a peripheral unit, the virtual processing unit being implemented by a physical processing unit connected to the peripheral unit, the method comprising a step of transmitting to the peripheral unit a request sent by the virtual processing unit to access a service provided by the peripheral unit, the access request comprising at least one parameter and an identifier of the virtual unit, the method comprising steps, executed by the peripheral unit after receiving an access request, of allocating a set of registers to the virtual unit identifier received, storing the parameter received in the register set allocated, and when the peripheral unit is available for processing a request, selecting one of the register sets, and triggering a process in the peripheral unit from the parameters stored in the selected register set.

Method for enabling several virtual processing units to directly and concurrently access a peripheral unit

A method of generating electrical energy in an integrated circuit that may include setting into motion a (3D) three-dimensional enclosed space in the integrated circuit. The 3D enclosed space may include a piezoelectric element and a free moving object therein. The method may also include producing the electrical energy from impact between the free moving object and the piezoelectric element during the motion.

The present disclosure relates to a method of processing an interrupt comprising a peripheral unit sending an interrupt, the interrupt being intended for a virtual unit executed by a processing unit, transmitting the interrupt to an interrupt control unit coupled to a processing unit, and the interrupt control unit storing the interrupt in an interrupt register. According to an embodiment of the present disclosure, the interrupt is transmitted to the interrupt control unit in association with an identifier of the virtual unit receiving the interrupt, the interrupt register in which the interrupt belonging to a set of registers is stored comprising one interrupt register per virtual unit likely to be executed by the processing unit, the interrupt being transmitted to the processing unit if the virtual unit receiving the interrupt is being executed by the processing unit.
