PROGRAM INSTRUCTION INTERPRETATION

摘要

PROBLEM TO BE SOLVED: To provide a program instruction interpretation. SOLUTION: Program instructions in the form of a Java bytecode can be subjected to fixed mapping to processing operation or programmable mapping to processing operation. A system is obtained which is provided with a fixed mapping hardware interpreter, a programmable mapping hardware interpreter, and a software interpreter. The fixed mapping hardware interpreter provides high speed interpretation of the common and simple bytecodes. The programmable mapping hardware interpreter provides 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.
