  • Patent number: 10248576
    Abstract: The present invention provides a DRAM/NVM hierarchical heterogeneous memory system with software-hardware cooperative management schemes. In the system, NVM is used as large-capacity main memory, and DRAM is used as a cache to the NVM. Some reserved bits in the data structure of TLB and last-level page table are employed effectively to eliminate hardware costs in the conventional hardware-managed hierarchical memory architecture. The cache management in such a heterogeneous memory system is pushed to the software level. Moreover, the invention is able to reduce memory access latency in case of last-level cache misses. Considering that many applications have relatively poor data locality in big data application environments, the conventional demand-based data fetching policy for DRAM cache can aggravates cache pollution.

  • Patent number: 9552250
    Abstract: Discovering a hardware failure in a processor is disclosed. When an operating system or application fails, a function containing the instruction that failed along with the register set of the CPU at the failure is recorded. The function is analyzed into its basic blocks. The failing instruction, the failing basic block, the definitions that reach the failing instruction, and the CPU register set at the failure provide information to determine whether the failure was caused by hardware or software. If, after a complete search of the definitions reaching the failing instruction, the search discovers a first definition defining the failing instruction and a second definition defining the first definition such that the second definition reaches the failing instruction and the first definition assigns a register value that does not match a register value in the failing instruction, then a hardware failure is the cause of the crash.
