Abstract :
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 μPC of memory operations by 29% on average compared to the previous hardware scheme.
