Pcie traffic tracking hardware in a unified virtual memory system

摘要: Techniques are disclosed for tracking memory page accesses in a unified virtual system. An access unit detects generated by first processor accessing system of second processor. The determines whether cache includes an entry the page. If so, then increments associated counter. Otherwise, attempts to find unused that is available allocation. associates with page, and sets counter initial value. selects valid memory; clears bit; page; initializes
