Abstract: A heterogeneous processor architecture and a method of booting a heterogeneous processor is described. A processor according to one embodiment comprises: a set of large physical processor cores; a set of small physical processor cores having relatively lower performance processing capabilities and relatively lower power usage relative to the large physical processor cores; and a package unit, to enable a bootstrap processor. The bootstrap processor initializes the homogeneous physical processor cores, while the heterogeneous processor presents the appearance of a homogeneous processor to a system firmware interface.

Abstract: Embodiments of the invention relate to a method and apparatus for a zero voltage processor sleep state. A processor may include a dedicated cache memory. A voltage regulator may be coupled to the processor to provide an operating voltage to the processor. During a transition to a zero voltage power management state for the processor, the operational voltage applied to the processor by the voltage regulator may be reduced to approximately zero and the state variables associated with the processor may be saved to the dedicated cache memory.

Abstract: A system and method for fencing memory accesses. Memory loads can be fenced, or all memory access can be fenced. The system receives a fencing instruction that separates memory access instructions into older accesses and newer accesses. A buffer within the memory ordering unit is allocated to the instruction. The access instructions newer than the fencing instruction are stalled. The older access instructions are gradually retired. When all older memory accesses are retired, the fencing instruction is dispatched from the buffer.

Abstract: In one embodiment, a processor includes at least one execution unit and Return Oriented Programming (ROP) detection logic. The ROP detection logic may determine a ROP metric based on a plurality of control transfer events. The ROP detection logic may also determine whether the ROP metric exceeds a threshold. The ROP detection logic may also, in response to a determination that the ROP metric exceeds the threshold, provide a ROP attack notification.

Abstract: In one embodiment, a processor includes at least one execution unit. The processor also includes a Return Oriented Programming (ROP) logic coupled to the at least one execution unit. The ROP logic may validate a return pointer stored on a call stack based on a secret ROP value. The secret ROP value may only be accessible by the operating system.
