MICROPROCESSOR EXTENDED INSTRUCTION SET MODE |
摘要 |
<p>Disclosed is a system and method of adding functionality to a microprocessor, especially a RISC machine having a plurality of cores, with minimal changes in circuitry and while maintaining legacy features. An enhancement to the microprocessor involves modifying a program counter register (P-register). This invention increases the number of bits in the P-register from 9 to 10. A tenth bit signals an extended instruction mode. When the tenth bit is not set, microprocessor instructions perform legacy functions. When the tenth bit is set, the extended instruction mode is active and instructions perform different or enhanced functions.</p> |
