摘　　要：针对Java技术在嵌入式领域的广泛应用,设计了一个适用于低端嵌入式设备的32位环境的Java处理器JPOR。该处理器由FPGA芯片实现,采用一种新的Java栈结构,指令系统简洁,可以直接执行Java字节码,能够对实时Java规范(RTSJ)提供有效支持。在Xilinx SPARTAN-3平台上通过了功能仿真,表明该Java处理器能够在低成本的FPGA芯片中实现。With the Java technology widespread applied in the embedded system domain, a Java processor with a 32-bit environment optimized For RTSJ is designed, and is suitable for low power embedded equipments. The processor is implemented by a FPGA chip, which has a new kind of Java stack structure and has a very simple instruction system. It can exeute the Java byte code directly, and provide effective support to the real-time specification for Java. It passes the function simulation in the Xilinx SPARTAN-3 platform, which shows that the Java processor can be implemented in the low cost FPGA chip.
