Abstract:
The invention relates to a data processing system and a date processing method. The data processing system is configured to perform a hardware transactional memory (HTM) transaction. The data processing system comprises a byte-addressable nonvolatile memory for persistently storing data and a processor being configured to execute an atomic HTM write operation in connection with committing the HTM transaction by writing an indicator to the nonvolatile memory indicating the successful commit of the HTM transaction.
