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.

这项工作的目的是加快互联网流行的编程语言的执行，即拼写languagessuch，例如JavaScript和Python。这些语言易于使用，因为不需要声明所有变量。但是，这使它们非常有效地编译。在这项工作中，首席研究员将设计专门配备有助于加速这些语言的产品。鉴于这些语言的重要性延迟了开发，有效的技术可以加快其持续开发网络基础架构的基础。这种发展对于我们的社会的效率，竞争力和福祉至关重要。首席研究者将专注于几种技术。其中一种是使用猜测支持来执行代码最有可能的执行路径，如果采取了另一种路径，则撤销执行。另一种技术是预测，以预测将执行代码的哪些部分。最后，第三种技术是重复使用，处理器将在其结构中保持足够的状态，以在相同功能的调用中重新使用。
