Adaptive access control for hardware blocks

A system for providing access to slave side memory resources based on an identity of a master side entity, comprising:

• a memory unit for storing instructions;
• and
• a processor unit coupled to the memory unit and configured to:
• determine a current access owner;
• receive a memory access command from the master side entity;
• process the memory access command based on a domain mask associated with the master side entity if the master side entity is the current access owner;
• if the master side entity is not the current access owner, then
• invalidate all existing keys;
• determine the domain mask associated with the master side entity;
• process the memory access command based on the domain mask associated with the master side entity;
• and
• set the current access owner equal to the master side entity.

An apparatus for providing access to slave side memory resources based on an identity of a master side entity, comprising:

• means for determining a current access owner;
• means for receiving a memory access command from the master side entity;
• means for processing the memory access command based on a domain mask associated with the master side entity if the master side entity is the current access owner;
• if the master side entity is not the current access owner, then
• means for invalidating all existing keys;
• means for determining the domain mask associated with the master side entity;
• means for processing the memory access command based on the domain mask associated with the master side entity;
• and
• means for setting the current access owner equal to the master side entity.

A non-transitory processor-readable storage medium comprising instructions for providing access to slave side memory resources based on an identity of a master side entity, comprising:

• code for determining a current access owner;
• code for receiving a memory access command from the master side entity;
• code for processing the memory access command based on a domain mask associated with the master side entity if the master side entity is the current access owner;
• if the master side entity is not the current access owner, then
• code for invalidating all existing keys;
• code for determining the domain mask associated with the master side entity;
• code for processing the memory access command based on the domain mask associated with the master side entity;
• and
• code for setting the current access owner equal to the master side entity.
