HARDWARE APPARATUSES AND METHODS FOR MEMORY PERFORMANCE MONITORING

摘要

Methods and apparatuses relating to memory performance monitoring are described. In one embodiment, a processor includes at least one core, a performance monitoring unit, and a memory management unit including a first allocator to allocate a first virtual memory region of a memory for a first data structure, a second allocator to allocate a second, different virtual memory region of the memory for a second data structure, wherein the memory management unit is to, for each memory access request from the at least one core, set a monitor flag when a virtual address of a memory access request is in the first virtual memory region and set the monitor flag when the virtual address of the memory access request is in the second, different virtual memory region, and enable the performance monitoring unit to monitor the memory access request when the monitor flag is set.
