<p>A microprocessor architecture (30) for executing byte compiled Java programs directly in hardware. The microprocessor targets the lower end of the embedded systems domain and features two orthogonal programming models, a Java model and a RISC model. The entities share a common data path and operate independently, although not in parallel. The microprocessor includes a combined register file in which the Java module (31) sees the elements in the register file (35) as a circular operand stack and the RISC module (33) sees the elements as a conventional register file. The integrated microprocessor architecture facilitates access to hardware-near instructions and provides powerful interrupt and instruction trapping capabilities.</p> |
