The present invention relates to a device (10) for accelerating the interpretation of a program in interpreted language, said program comprising an intermediate code which can be executed by a virtual machine in the form of successive tasks, said device comprising routing means (13) able to extract a current intermediate code from a memory (11) in order to load it into storage means (16). When there is a request for a change of task, the routing means (13) are able to inhibit the extraction of the current intermediate code and to load into the storage means (16) a reserved intermediate code intended to effect a saving of a context of the virtual machine.
