摘要： 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.

摘要： 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.
摘要翻译：构建了本机（RISC或CISC）微处理器和堆栈（Java（TM））机器，以便Java（TM）VM指令可以在硬件中执行。大多数Java（TM）指令都是直接执行的，而诸如操作Java（TM）对象的那些更复杂的Java TM指令被执行为本地微代码。为了使本地微代码指令访问Java（TM）操作数堆栈，Java（TM）操作数堆栈指针指向作为堆栈当前顶部的寄存器文件位置，而状态寄存器中的重映射位指示寄存器在本地指令中指定的内容将重新映射为最大Java（TM）操作数堆栈指针值减去Java（TM）操作数堆栈指针的当前值。
