Protection zones in virtualized physical addresses for reconfigurable memory systems using a memory abstraction

摘要

Systems and methods define a memory system using an abstracted memory protocol that enables virtual to physical mapping of memory address requests at an abstracted memory module. A memory abstraction unit abstracts timing and naming of memory requests from one or more clients to timing and naming at one or more memory devices. The memory abstraction unit includes abstracted memory protocol logic for interpreting the memory requests from the one or more clients. The memory abstraction unit also includes mapping logic for translating the naming defined by a memory access request by a requesting client to a virtual physical address at a selected protection zone in at least one of the one or more memory devices and memory control logic for accessing the one or more memory devices at the virtual physical address.

1. An apparatus, comprising:
a memory abstraction unit configured for abstracting naming of memory access requests from one or more clients to naming at one or more memory devices, the memory abstraction unit comprising:
abstracted memory protocol logic for interpreting the memory requests from the one or more clients;mapping logic for translating an address defined by the naming of the memory access request by a requesting client of the one or more clients to a virtual physical address at a selected protection zone in at least one of the one or more memory devices; andmemory control logic for accessing the one or more memory devices at the virtual physical address; wherein the selected protection zone has been previously defined and allocated to the requesting client by the memory abstraction unit.
