In one embodiment, the present invention includes a method for associating a first identifier with data stored by a first agent in a cache line of a cache to indicate the identity of the first agent, and storing the first identifier with the data in the cache line and updating at least one of a plurality of counters associated with the first agent in a metadata storage in the cache, where the counter includes information regarding inter-agent interaction with respect to the cache line. Other embodiments are described and claimed.

A hardware profiling mechanism implemented by performance monitoring hardware enables page level automatic binary translation. The hardware during runtime identifies a code page in memory containing potentially optimizable instructions. The hardware requests allocation of a new page in memory associated with the code page, where the new page contains a collection of counters and each of the counters corresponds to one of the instructions in the code page. When the hardware detects a branch instruction having a branch target within the code page, it increments one of the counters that has the same position in the new page as the branch target in the code page. The execution of the code page is repeated and the counters are incremented when branch targets fall within the code page. The hardware then provides the counter values in the new page to a binary translator for binary translation.

摘要:
A method and apparatus for hardware-based dynamic escape detection in managed run-time environments are described. In one embodiment, the method includes the detection of a pointer update of a first object having a global scope. In one embodiment, a single instruction is issued to assert that a scope attribute associated with a target object of the pointer update identifies a global scope. The single instruction may return failure if the scope attribute that is associated with the second object identifies the scope of the second object as local. Verification may include the reading of an object descriptor for the second object to determine whether a scope attribute of the object descriptor indicates that the scope of the second object is local. Once verified, in one embodiment, the second object, and each object reachable from the second object, are converted into global objects. Other embodiments are described and claimed.
