摘要： A processing device features a processing unit, a memory management system, and persistent memory in a persistent memory domain. The processing device provides an enhanced write-back (WB-E) memory space for an application running on the processing unit. The memory management system maps the WB-E memory space to the persistent memory. The application creates WB-E data by executing an instruction to store data to an address in the WB-E memory space. The WB-E data is automatically stored in a cache associated with the processing unit in response to creation of the WB-E data by the application. In response to execution of a commit instruction by the application after the application has created WB-E data for multiple memory addresses, the memory management system automatically ensures that all of the WB-E data for the application has been saved to the persistent memory domain. Other embodiments are described and claimed.
