ABSTRACT:
A processing device comprises an instruction memory120for storing virtual machine instructions, such as Java byte codes. A processor112of the processing device comprises a predetermined microcontroller core114for executing native instructions from a predetermined set of microcontroller specific instructions. The native instructions differ from the virtual machine instructions. The processor112is of a type which may request re-feeding of a plurality of native instructions. For instance, the processor112may have a pipeline and/or instruction cache which after an interrupt need to be re-filled.The processing device comprises a pre-processor130with a converter132for converting at least one virtual machine instruction, fetched from the instruction memory, into at least one native instruction. Feeding means136of the pre-processor130feed native instructions to the microcontroller core114and re-feed native instructions in response to the processor requesting re-feeding of a number of native instructions.
