Abstract
A combined native (RISC or CISC) microprocessor and stack (Java™) machine are constructed so that Java™ VM instructions can be executed in hardware. Most Java™ instructions are executed directly, while more complex Java™ instructions, such as those manipulating Java™ objects, are executed as native microcode. In order for native microcode instructions to access the Java™ operand stack, a Java™ operand stack pointer points to the register file location that is the current top of the stack, while a remap bit in the status register indicates that registers specified in native instructions are remapped as the maximum Java™ operand stack pointer value minus the present value of the Java™ operand stack pointer.
