  • Patent number: 9804969
    Abstract: A method includes receiving an instruction to be executed by a processor. The method further includes performing a lookup in a page crossing buffer that includes one or more entries to determine if the instruction has an entry in the page crossing buffer. Each of the entries includes a physical address. The method further includes, when the page crossing buffer has the entry in the page crossing buffer, retrieving a particular physical address from the entry in the page crossing buffer.

  • Publication number: 20170090922
    Abstract: A method implemented by a central processing unit (CPU), comprising decoding a first instruction word of a first instruction pair, wherein the first instruction word comprises a first operation code identifying a first operation, storing the first operation code in a register memory upon decoding the first instruction word, decoding a second instruction word of the first instruction pair, wherein the second instruction word comprises a first operand, generating a first decoded instruction pair by combining the first operation code stored in the register memory with the first operand in the second instruction word. The method further comprises executing the first decoded instruction pair by performing the first operation on the first operand.

  • Patent number: 9489204
    Abstract: An example method of storing a partial target address in an instruction cache includes receiving a branch instruction. The method also includes predicting a direction of the branch instruction as being not taken. The method further includes calculating a destination address based on executing the branch instruction. The method also includes determining a partial target address using the destination address. The method further includes in response to the predicted direction of the branch instruction changing from not taken to taken, replacing an offset in an instruction cache with the partial target address.

  • Publication number: 20160246731
    Abstract: A translation lookaside buffer (TLB) stores translation entries. The translation entries include a virtual address, a physical address and a memory local/not-local flag. When a processor is in a low power/local memory mode a virtual address is received. A matching translation entry has a local/not-local flag. Upon the local/not-local flag indicating the physical address of the matching translation entry being outside the local memory, an out-of-access-range memory access exception is generated.

  • Publication number: 20160092668
    Abstract: A system for authorizing an operation is provided. The system may acquire motion data collected by a wearable device. A mobile terminal may determine whether the motion data matches with a physical motion for verification. If the motion data matches with the physical motion for verification, the mobile terminal may be authorized to perform a predetermined operation corresponding to the physical motion for verification. Thus, a user's identity may be verified based on the wearable device that collects motion data.
