Abstract: The present invention relates to the field of communication technologies and discloses a method and an apparatus for encoding a data address, so that attacks can be effectively prevented and resources and costs required to handle a bank conflict are reduced. In solutions provided by embodiments of the present invention, an exclusive-OR operation is performed on one or more bits of a received uncoded address by using multiple preset transform polynomials; and an encoded address is obtained according to a result of the exclusive-OR operation. The solutions provided by the embodiments of the present invention are applicable to designs that require a large-capacity DRAM, high performance and high reliability, and have an anti-attack demand.

Abstract: The present invention discloses a data caching method and apparatus, and relates to the field of network applications. The method includes: receiving a first data request; writing target data in the first data request into an on-chip Cache, and counting a storage time of the target data in the on-chip cache; enabling a delay expiry identifier of the target data when the storage time of the target data in the Cache reaches a preset delay time; and releasing the target data when the delay expiry identifier of the target data is in an enabled state and processing of the target data is complete.
