    摘要: A method, apparatus and system are disclosed for decoding an instruction in a variable-length instruction set. The instruction is one of a set of new types of instructions that uses a new escape code value, which is two bytes in length, to indicate that a third opcode byte includes the instruction-specific opcode for a new instruction. The new instructions are defined such the length of each instruction in the opcode map for one of the new escape opcode values may be determined using the same set of inputs, where each of the inputs is relevant to determining the length of each instruction in the new opcode map. For at least one embodiment, the length of one of the new instructions is determined without evaluating the instruction-specific opcode.

    摘要: Apparatuses and methods for steering SMM code region accesses are disclosed. In one embodiment, an apparatus includes a status indicator, a base storage location, and an abort storage location. The status indicator is to indicate whether the apparatus is operating in SMM. The base storage location is to store a base address and the abort storage location is to store an abort address. The base address is to specify a first memory address region at which SMM code is to be accessed. The abort address is to specify a second memory address region to which accesses to the first memory address region are to be steered if the apparatus is not operating in SMM.
