SHF: Small: Computer Architecture for Scripting Languages

点击翻译按钮获取中文摘要

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.
