Abstract: 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.

Key words: Java processor, RTSJ, real-time Java platform, stack frame
