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.

Encoding a data address using XOR operation wherein address bits are transformed by multiple preset polynomials

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.

On-chip data caching method and apparatus

Embodiments of the present invention relate to a signal order-preserving method and apparatus. When data of a request signal that comes from a corresponding first upstream device is written into a first first input first output (FIFO) memory, invalid data is written into a second FIFO memory corresponding to a second upstream device in a same clock cycle; and the data of the request signal is read from the first FIFO memory, the invalid data is read from the second FIFO memory, the invalid data is discarded, and the data of the request signal is conveyed to a downstream device. Through the signal order-preserving method and apparatus in the embodiments of the present invention, the coupling extent between devices on which there is an order-preserving requirement is reduced while signal order-preserving is achieved.
