为了在龙芯2E处理器上建立稳定的Java运行环境,丰富龙芯平台的上层软件库,以Kaffe这款开源Java虚拟机为移植对象,分析了其运行机制,确定了其代码结构中平台相关的3个主要模块:SysCallMethod、Trampoline和JTT,并结合龙芯2E处理器的特点,给出了相关模块的修改方案.最后用第三方的测试标准对移植后的虚拟机进行了测试,表明了移植的有效性.

To build a Java run-time environment on Godson 2E, expand the software library of Godson platform, Kaffe, an open source JVM developed for research work is chose for the Transplantation. By analyzing the structure of Kaffe, the three key modules which depend on the platform are SysCallMethod, Tranpoline and JIT. Based on the features of Godson 2E, the solution of porting for the modules is proposed. The testing result of third party benchmark shows that the solution is feasible and the transplantation is successful.
