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.

这项工作的目标是加速执行互联网上最流行的编程语言，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，首席研究人员将指定专门配备的处理器硬件，以帮助加速这些语言。考虑到这些语言对Web开发的重要性，加快其执行速度的有效技术对于Web基础设施的持续开发是至关重要的。这样的开发对我们社会的效率、竞争力和福祉至关重要。首席调查员将专注于几项技术。其中一项技术是使用推测支持来执行代码最可能的执行路径，如果采取另一条路径，则撤消执行。另一种技术是预测，预测代码的哪些部分将被执行。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，以便在相同函数的调用中重用它。
