Zusammenfassung:A processing system includes a microprocessor, a hardware decoder arranged within the microprocessor, and a translator operatively coupled to the microprocessor. The hardware decoder is configured to decode instruction code non-native to the microprocessor for execution in the microprocessor. The translator is configured to form a translation of the instruction code in an instruction set native to the microprocessor and to connect a branch instruction in the translation to a chaining stub. The chaining stub is configured to selectively cause additional instruction code at a target address of the branch instruction to be received in the hardware decoder without causing the processing system to search for a translation of additional instruction code at the target address.
