  • Patent number: 7457738
    Abstract: In order to decode a simulation instruction in accordance with the present invention, a new decoding program is generated, which includes flat-type decoding codes for at least one of the instructions having a high occurrence frequency. The remaining instructions are decoded using tree-type decoding codes. By combining both flat-type and tree-type decoding operations in a single decoding program, simulation speed is increased while reducing memory requirements.
