Device to accelerate the interpretation of a program language interpreter

This invention conoeme a device (10) for accelerating the interpretation of a program in interpreted language, said program comprising executable intermediate code by a virtual machine and being executed in the form of successive tasks, said device comprising means routing (13) adapted to extract a current of a memory intermediate code (11) to load it into the storage means (16). At a change request tasks, the routing means (13) are adapted to inhibit the extraction of the current intermediate code and to load into the storage means (16) a reserved intermediate code for performing a backup of a context of the virtual machine.
