| 摘 要： | 软件流水是一种开发循环程序指令级并行性的技术, 它通过并行执行连续的多个迭代来加快循环的执行速度。而在逆向工程中，软件流水却为逆向翻译带来了困难。为此，基于IA-64平台，提出了一种反流水算法，针对循环中包含软件流水的汇编代码进行处理，将其反向转换成语义等价的串行代码，并通过实验验证了该算法的有效性,为在二进制翻译中处理软件流水代码奠定了基础。

| Abstract: | Software pipelining is a loop scheduling technique which extracts instruction level parallelism by overlapping the execution of several consecutive iterations. But in reverse engineering, it causes some difficulties to reverse translation. A de-pipelining algorithm based on the IA-64 architecture was proposed. This algorithm reversely converted the optimized assembly code of a software-pipelined loop to a semantically equivalent sequential counterpart. The experimental results have verified the validity of the proposed de-pipellning, which provides the basis for processing software pipelining in the binary translation. |
