SHF: Small: Computer Architecture for Scripting Languages

这项工作的目标是加快互联网上最流行的编程语言的执行速度，即脚本语言，如JavaScript和Python。这些语言很容易使用，因为它们不需要声明所有的变量。然而，这使得它们很难有效地编译。在这项工作中，首席研究员将设计专门配备的处理器硬件来帮助加快这些语言的速度。考虑到这些语言对web开发的重要性，加速其执行的有效技术是web基础设施持续发展的基础。这样的发展对我们社会的效率、竞争力和福祉至关重要。首席研究员将专注于几种技术。其中之一是使用推测支持来执行代码的最有可能的执行路径，如果采用另一条路径，则撤销执行。另一种技术是预测，预测代码的哪一部分将被执行。最后，第三种技术是重用，处理器将在其结构中保留足够的状态，以便跨相同函数的调用进行重用。

The goal of this work is to speed-up the execution of themost popular programming languages of the internet, namely Scripting Languagessuch as JavaScript and Python. These languages are easy to use, becausethey do not require declaring all the variables. However, this makes them veryhard to compile efficiently. In this work, the principal investigator will designprocessor hardware that is specifically equipped to help speed-upthese languages. Given the importance of these languages forweb development, effective techniques to speed-up their executionare fundamental for the continued development of theweb infrastructure. Such development is crucial to oursociety's efficiency, competitiveness, and wellbeing.The principal investigator will focus on several techniques.One of them is using speculation support to execute the most likelyexecution path of the codes, and undo the execution if another pathwas taken instead. The other technique is prediction, to predict whichparts of the code will be executed. Finally, the third technique is reuse, where theprocessor will keep enough state in its structures to reuseit across invocations of the same functions.
