Abstract
Methods and apparatus for control of On-Die System Fabric (OSF) blocks are described. In one embodiment, a shadow address corresponding to a physical address may be stored in response to a user-level request and a logic circuitry (e.g., present in an OSF) may determine the physical address from the shadow address. Other embodiments are also disclosed.
Claims30
An apparatus comprising:
- an On-die System Fabric (OSF) to couple a processor to a logic block;
- and
- a memory to store a shadow address corresponding to a physical address in response to a user-level request,
- wherein the OSF is to comprise logic to determine the physical address from the shadow address.
1 more element
A method comprising:
- in response to a user-level request, allocating a portion of a memory for storage of a shadow address corresponding to a physical address;
- and
- determining, at an OSF, the physical address from the shadow address.
A system comprising:
- an input/output (IO) device;
- an On-die System Fabric (OSF) to couple a processor to the IO device;
- and
- a memory to store a shadow address corresponding to a physical address in response to a user-level request,
- wherein the OSF is to comprise logic to determine the physical address from the shadow address.
