| Virtual machines (VMs) such as the Java VM are a popular format for running architecture- neutral code in a managed runtime. Such VMs are typically implemented using a combi- nation of interpretation and just-in-time compilation (JIT). A significant challenge for the portability of VM code is the growing popularity of multi-core architectures with special- ized processing cores aimed at computation-intensive applications such as media processing. Such cores differ greatly in architectural design compared to traditional desktop processors. One such processing core is the Cell Broadband s (Cell BE) Synergistic Processing Element (SPE). An SPE is a light weight VLIW processor core with a SIMD vector instruc- tion set. In this paper we investigate some popular interpreter optimizations and introduce new optimizations exploiting the special hardware properties offered by the Cell BE's SPE. |
