Abstract: Embodiments described herein may include apparatus, systems, techniques, or processes that are directed to optimizing memory access and minimizing performance degradation due to faulty or malicious devices attempting to access improper memory locations. Faulty/malicious devices' memory accesses are quickly blocked reducing performance degradation due to the avoidance of costly memory lookups and fault generation/processing. Other embodiments may be described and/or claimed.

Abstract: An apparatus and method are described for performing split lock operations in a multi-core processor.

Abstract: A processor of an aspect includes a plurality of caches at a plurality of different cache levels. The processor also includes a decode unit to decode a fetch instruction. The fetch instruction is to indicate address information for a memory location, and the fetch instruction is to indicate a cache level of the plurality of different cache levels. The processor also includes a cache controller coupled with the decode unit, and coupled with a cache at the indicated cache level. The cache controller, in response to the fetch instruction, is to store data associated with the memory location in the cache, wherein the fetch instruction is architecturally guaranteed to be completed. Other processors, methods, systems, and machine-readable storage mediums storing instructions are disclosed.
