Zusammenfassung:According to one general aspect, an apparatus may include a memory configured to store both data and metadata, such that for portions of data associated with the metadata, the data and metadata are interleaved such that a unit of metadata succeeds each power of two contiguous units of data. The apparatus may also include a memory manager circuit. The memory management circuit may be configured to receive a data access to the memory, wherein the data access includes a public memory address. The memory management circuit may be configured to determine if the public memory address is associated with metadata. The memory management circuit may be configured to, if so, convert the public memory address to a private memory address. The memory management circuit may be configured to complete the data access at the private memory address.
