Title: Accelerating Dynamically Typed Languages with a Virtual Function Cache
Abstract: Dynamically typed languages are increasingly important to programmers of all levels because they allow for extended class hierarchies with shared interfaces and inheritance. Virtual functions are a key element in implementing these interesting and useful features. However, virtual functions are more costly than static equivalents, so they are often avoided either in code or by aggressive compiler optimizations. This summer, Professor Stratton and I designed, implemented, and did preliminary tests of hardware support for the execution of virtual function calls in the form of a Virtual Function Cache. By providing support to virtual functions at the hardware level, we aim to improve overall performance of dynamically typed languages and other applications of indirect function calls so that programmers can reap the benefits of these features without suffering performance costs.
