摘要

我们试图为芯片多处理器(CMP)环境中多线程工作负载的快速有效边界检查提供体系结构支持。边界信息共享和智能标记有助于更有效地利用指针的特征执行边界检查。此外，BCache架构允许快速访问边界信息。仿真结果表明，与之前的硬件方案相比，该方案平均提高了¥ìPC内存操作量。

Scalable and Efficient Bounds Checking for Large-Scale CMP Environments

We attempt to provide an architectural support for fast and efficient bounds checking for multithread work-loads in chip-multiprocessor (CMP) environments. Bounds information sharing and smart tagging help to perform bounds checking more effectively utilizing the characteristics of a pointer. Also, the BCache architecture allows fast access to the bounds information. Simulation results show that the proposed scheme increases ¥ìPC of memory operations by 29% on average compared to the previous hardware scheme.
