发明名称 Method for enabling several virtual processing units to directly and concurrently access a peripheral unit
摘要 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.
