    • A microprocessor architecture 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 sees the elements in the register file as a circular operand stack and the RISC module 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.
    • 用于直接在硬件中执行字节编译的Java程序的微处理器架构。 微处理器面向嵌入式系统领域的下端,并具有两个正交编程模型,即Java模型和RISC模型。 实体共享一个共同的数据路径并独立运行,尽管不是并行的。 微处理器包括一个组合寄存器文件,其中Java模块将寄存器文件中的元素视为循环操作数堆栈,并且RISC模块将元素视为常规寄存器文件。 集成的微处理器架构便于访问靠近硬件的指令,并提供强大的中断和指令捕获功能。

    • A system and method for preserving power in a microprocessor pipeline. The system includes a register file read control unit, the read control unit being configured to monitor one or more outputs from a control/decode unit of the pipeline and monitor write addresses from one or more other stages of the pipeline. The system also includes one or more read inhibit units each having an input, an output, and an enable terminal, the output of each of the one or more read inhibit units being coupled to a unique register port of a register file within the pipeline. The input of each of the one or more read inhibit units being coupled to the control/decode unit, and the enable terminal of each of the one or more read inhibit units being coupled to a unique output of the read control unit.
    • 一种用于在微处理器管道中保持功率的系统和方法。 所述系统包括寄存器文件读取控制单元,所述读取控制单元被配置为监视来自所述流水线的控制/解码单元的一个或多个输出并且监视来自所述流水线的一个或多个其他阶段的写入地址。 该系统还包括一个或多个读取禁止单元,每个读取禁止单元各自具有输入,输出和使能端,所述一个或多个禁止读取单元中的每一个的输出耦合到流水线内的寄存器文件的唯一寄存器端口。 一个或多个禁止读取单元中的每一个的输入耦合到控制/解码单元,并且一个或多个禁止读取单元中的每一个的使能端耦合到读取控制单元的唯一输出。
