The Need for Fast Communication in Hardware - Based Speculative Chip

摘要

Chip-multiprocessor (CMP) architectures are a promising design alternative to exploit the ever-increasing number of transistors that can be put on a die. To deliver high performance on applications that cannot be easily parallelized, CMPs can use additional support for speculatively executing the possibly data- Dependent threads of an application. For cross-thread dependences that must be Handled dynamically, the threads can be made to synchronize and communicate Either at the register level or at the memory level.
