  • Error recovery method and apparatus
    Patent number: 11604711
    Abstract: An error recovery method and apparatus, and a system are disclosed. At least two CPUs in a lockstep mode can exit the lockstep mode when an error occurs in at least one CPU, and the CPU in which the error occurs and a type of the error are determined. When the error can be recovered, the CPU in which the error occurs can be recovered according to a correctly running CPU. This helps the at least two CPUs run again at a position at which a service program is interrupted.
    Type: Grant

  • Efficient Instruction Pair for Central Processing Unit (CPU) Instruction Design
    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.
