  • Program instruction interpretation
    Publication number: 20040015896
    Abstract: Program instructions in the form of Java bytecodes may be subject to fixed mappings to processing operations or programmable mappings to processing operations. A system is provided with a fixed mapping hardware interpreter, a programmable mapping hardware interpreter and a software interpreter. The fixed mapping hardware interpreter is able to provide high speed interpretation of the common and simple bytecodes. The programmable mapping hardware interpreter is able to provide high speed interpretation of the simple and performance critical programmable bytecodes with the remaining bytecodes and more complicated bytecodes being handled by the software interpreter.

  • Configuration control within data processing systems
    Publication number: 20020199087
    Abstract: A data processing system is provided with a first mechanism for executing instructions of a first instruction set and a second mechanism for executing instructions of a second instruction set. The second mechanism requires configuration data 310, 312, 314, 316 which may or may not be valid. Programs that use the second execution mechanism are responsible for the writing of its own configuration data with this being indicated as being necessary by a configuration valid indicator CV set to indicate that the configuration is invalid by the operating system 300 upon detecting an appropriate process switch.
