摘要： A platform and method for secure handling of events in an isolated environment. A processor executing in isolated execution “IsoX” mode may leak data when an event occurs as a result of the event being handled in a traditional manner based on the exception vector. By defining a class of events to be handled in IsoX mode, and switching between a normal memory map and an IsoX memory map dynamically in response to receipt of an event of the class, data security may be maintained in the face of such events.

摘要： A microprocessor uses broadcast state renaming to reduce processing delays and microcode overhead which would otherwise result from rebroadcasts of state due to register renaming. The microprocessor comprises a memory execution unit, a microcode sequencer, and various functional units. The memory execution unit includes a segment register, content of which represents state of the processor. The microcode sequencer sets an identifier field in at least some microinstructions, indicating which of multiple copies of broadcast state are to be used in processing each such microinstruction. Each functional unit receives and internally stores multiple copies of broadcast state, each of which may correspond to a different renamed version of the segment register. Each functional unit selects, based on the identifier field of a microinstruction, one of its internally stored copies of broadcast state for use in processing the microinstruction.

摘要： In one embodiment, a method for flow optimization and prediction for vector streaming single instruction, multiple data (SIMD) extension (VSSE) memory operations is disclosed. The method comprises generating an optimized micro-operation (μop) flow for an instruction to operate on a vector if the instruction is predicted to be unmasked and unit-stride, the instruction to access elements in memory, and accessing via the optimized μop flow two or more of the elements at the same time without determining masks of the two or more elements. Other embodiments are also described.
