JE-Java芯片中取指部件的设计和性能分析

DESIGN AND PERFORMANCE ANALYSIS OF THE INSTRUCTION FETCH UNIT IN JE JAVA CHIP

首先介绍了 JE- Java芯片中取指部件的设计 .为了选择合适的指令预取策略和参数 ,需要对其进行性能分析 .利用理论分析和模拟两种方法对其进行性能分析 ,对指令预取策略和参数的选择提出了合理的建议 ,并与实际测试结果进行了比较 .

In the first section of this paper, the design of JE Java chip's instruction fetch unit is introduced. According to the performance analysis with the two methods of analysis model and simulation, an optimized set of system parameters and instruction pre fetch strategy are gained. It is shown that the results of the above two methods tally with the real ones of the JE Java chip.
