Abstract

Methods and apparatus for locking at least a portion of a shared memory resource. In one embodiment, an electronic device configured to lock at least a portion of a shared memory is disclosed. The electronic device includes a host processor, at least one peripheral processor and a physical bus interface configured to couple the host processor to the peripheral processor. The electronic device further includes a software framework that is configured to: attempt to lock a portion of the shared memory; verify that the peripheral processor has not locked the shared memory; when the portion of the shared memory is successfully locked via the verification that the peripheral processor has not locked the portion of the shared memory, execute a critical section of the shared memory; and otherwise attempt to lock the at least the portion of the shared memory at a later time.
