A true hardware read barrier

  title={A true hardware read barrier},
  author={Matthias Meyer},
Read barriers synchronize compacting garbage collection and application processing in a simple yet elegant way. Unfortunately, read barrier checks are expensive to implement in software, and even with hardware support, the clustering of read barrier faults irregularly impairs application progress to an unacceptable extent. For this reason, read barriers are often considered unsuitable for hard real-time systems.In this paper, we introduce a novel hardware read barrier design for an object-based… CONTINUE READING
