Compiler Techniques for Code Compression

该项目的目标是开发技术，以减少可执行代码的内存占用，以便允许越来越复杂的应用程序在有限的内存设备上执行，如手持计算机，个人数字助理和嵌入式处理器。近年来，计算机和计算设备已经融入到我们日常生活的许多方面。在许多情况下，可用于此类处理器的存储器的量受到诸如空间、重量和功耗之类的考虑的限制。同时，期望在这样的处理器上运行越来越复杂的应用。由于占用比在这样的处理器上可用的存储器更多的存储器的应用将不能在该处理器上运行，因此期望开发减少应用的存储器占用的技术。此外，它是必要的，压缩后的应用程序仍然是可执行的，因为对于正在考虑的应用领域，它是不可行的，以执行它的可执行文件的压缩。本项目调查的工具和技术的建设，以保持可执行性的方式进行代码压缩。

The goal of this project is to develop techniques to reduce the memory footprint of executable code, so as to allow more and more sophisticated applications to be executed on limited-memory devices, such as hand-held computers, personal digital assistants, and embedded processors. Recent years have seen the incorporation of computers and computational devices into many aspects of our everyday lives. In many cases, the amount of memory available for such processors is limited by considerations such as space, weight, and power consumption. At the same time, there is a desire to run more and more sophisticated applications on such processors. Since an application that occupies more memory than is available on such a processor will not be able to run on that processor, it is desirable to develop techniques to reduce the memory footprint of applications. Moreover, it is necessary that the compressed applications remain executable, since for the application domains under consideration it is not feasible to decompress the executable in order to execute it. This project investigates the construction of tools and techniques for code compression in a manner that preserves executability.
