Optimization when compiling six approaches are proposed : constant embedding , constant propagation , duplication propagation , flag update elimination , conditional instruction merge and instruction scheduling 編譯期優(yōu)化提出六種編譯期優(yōu)化的手段:只讀常量內(nèi)嵌,常量傳播,復(fù)制傳播,消除無用標(biāo)志位更新,條件語句合并和指令重排。
The thesis analysed the chief technique problems and designed the solution algorithms , proposed measures of the software fault tolerance techniques suitable for the hardware platform of the robotic system on the base of studying the two key techniques - eddi and cfcss . first , the thesis has done the analysis in theory for the chief technique problems including basic block partition , software signature instructions generation , shadow instructions generation and instructions scheduling , proposed the algorithms suitable for the target platform . then , the thesis introduces the design process of the software fault tolerance 本文在研究了sihft的兩項關(guān)鍵技術(shù)?復(fù)制簽名檢錯技術(shù)和軟件簽名控制流檢錯技術(shù)的基礎(chǔ)上,針對小型智能飛行機(jī)器人系統(tǒng)的硬件平臺,對軟件檢錯技術(shù)的關(guān)鍵問題進(jìn)行了分析并給出了解決問題的算法,提出了適于小型智能飛行機(jī)器人硬件平臺的軟件檢錯技術(shù)方案。
Based on these two factors mentioned above and the difficulty to implement in c compiler , this paper proposed a method of modifying operand type by inserting instruction lw or sw at assemble level as well as instruction scheduling . therefore , this can generate effective parallel instructions and correspondingly improve the performance and density of object code 本文在分析了上述兩個限制并行指令生成的主要因素以及很難在編譯器中實現(xiàn)并行指令生成的基礎(chǔ)上,提出了在匯編級檢查指令的操作數(shù)類型,通過插入lw或sw指令來改變操作數(shù)類型及指令調(diào)度的方法,能夠有效的生成并行指令,提高了代碼運行效率和代碼密度。
百科解釋
In computer science, instruction scheduling is a compiler optimization used to improve instruction-level parallelism, which improves performance on machines with instruction pipelines. Put more simply, without changing the meaning of the code, it tries to
