Compiler Techniques for Code Compression

这个项目的目标是开发技术来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，例如手持计算机、个人数字助理和嵌入式处理器。近年来，计算机和计算设备融入了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内存量受到空间、重量和功耗等因素的限制。同时，人们希望在这样的处理器上运行越来越复杂的应用程序。由于占用比这种处理器上的可用存储器更多的存储器的应用程序将不能在该处理器上运行，因此需要开发技术来减少应用程序的存储器占用。此外，压缩的应用保持可执行是必要的，因为对于所考虑的应用域，解压缩可执行文件以执行它是不可行的。本项目研究如何构建工具和技术，以便以保留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.
