本文以解决这些问题为背景，利用超标量指令流水原理设计了一个数学规划模型。

In order to solve these problems , a mathematical programming model was designed making use of principles of Superscalar Pipelining .

相关指令在流水中需要局部变量的值可以直接从旁路逻辑中得到，并在流水中完成局部变量值的全部使用。

Furthermore , in pipeline the values of local variables needed by dependent instructions may be directly gotten from bypassing logic , and some of them can complete all usage .

最后，将C代码作为输入数据，应用本文的语言转换方法和流水处理方法实现了从C代码到VHDL代码转换和两种流水方式&依据串行指令条数进行流水和依据时间进行流水。

Finally , makes the C code as input data , using the method of language transformation and pipelining technology introduced in this thesis to realize C code to VHDL code conversion and two pipelining ways ( the pipelining based instruction number and the pipelining based time ) .
