| 摘 要： | 协同设计虚拟机采用动态二进制翻译实现不同体系结构间的二进制兼容,对源指令的翻译和处理影响了协同设计虚拟机的启动性能.研究发现,在一个采用解释执行和翻译相结合的协同设计虚拟机中,处理非热点代码的解释执行是虚拟机启动开销的主要来源.发现了协同设计虚拟机中的解释例程局部性,并提出了一种硬件译码后指令缓存结构DICache(d...

| Abstract: | Co-designed virtual machines(co-VM) provide the processor designer with new opportunities for innovation through the combined hardware and software.Co-VM uses dynamic binary translation to implement binary compatibility between different instruction set architectures(ISA).Interpreting and translating the source ISA binaries will affect the startup performance of a co-VM.In the exploration of startup performance of our VM which employs interpretation and superblock translation,we observe that the cold code i... |
