DUAL-INTERFACE ADDRESS HARDWARE ARCHITECTURE SUITABLE FOR NVME NAMESPACE

摘要

A dual-interface address hardware architecture suitable for an NVMe namespace. A hardware comparing and sharing module architecture is mainly used for comparing different block addresses of dual interfaces, and a plurality of namespaces can be supported and configured. For a dual-interface design, one interface is a namespace configuration interface, and the other interface is a regional write encryption and decryption interface. The dual-interface design is used for simultaneously querying and reading a namespace characteristic value and encryption and decryption characteristic values, thereby effectively reducing the delay time of conversion between instruction operations. However, the definitions of two query block addresses are different. According to this design, before a memory space is integrated, an integrated dual-interface sharing part is separately compared, and the corresponding comparison result is obtained and used, thereby greatly reducing hardware design costs. Compared with the hardware before integration, the design has the advantage that two selectors and a set of comparison integrator can be saved corresponding to each namespace.
