<p>A processing device comprises an instruction memory (120) for storing virtual machine instructions, such as Java byte codes. A processor (112) of the processing device comprises a predetermined microcontroller core (114) for executing native instructions from a predetermined set of microcontroller specific instructions. The native instructions differ from the virtual machine instructions. The processor (112) is of a type which may request re-feeding of a plurality of native instructions. For instance, the processor (112) may have a pipeline and/or instruction cache which after an interrupt need to be re-filled. The processing device comprises a pre-processor (130) with a converter (132) for converting at least one virtual machine instruction, fetched from the instruction memory, into at least one native instruction. Feeding means (136) of the pre-processor (130) feed native instructions to the micontroller core (114) and re-feed native instructions in response to the processor requesting re-feeding of a number of native instructions.</p> |
