Abstract
In a processor system comprising of a processor having an instruction decoder, a general registercomposed of a plurality of register areas and at least one ALU, and a Java acceleratorfor converting a Java bytecode sequence to a native instruction sequence for the processor and supplying the native instruction sequence to the instruction decoder. The Java acceleratoris composed of a bytecode translatorfor converting the Java bytecode sequence to the native instruction sequence for the processor and a register status control unitfor mapping a Java operand stack to any of the register areas of the general register and detecting a bytecode redundant for the processor. When a redundant bytecode is detected by the register status control unit, the supply of the native instruction from the bytecode translatorto the instruction decoderis inhibited.
