摘要： PROBLEM TO BE SOLVED: To use a single physical register file under an alias to execute a floating point instruction and a pack data instruction. SOLUTION: A first instruction is received, it is determined whether the first instruction is the floating point instruction or a second type instruction, and it is determined whether a processor including first and second pairs of physical registers is in a floating point mode or in a second type mode. If the processor is in the second type mode when the first instruction is the floating point instruction, transition to the floating point mode is carried out, and the floating point instruction is operated by using the first pair of physical registers. If the processor is not in the floating point mode, transition to the second type mode is carried out, and the second type instruction is operated by using the second pair of physical registers partially under an alias to the first pair of physical registers so that the first pair of physical registers and the second pair of physical registers appear to be a single logical register file logically.

摘要： PROBLEM TO BE SOLVED: To install a set of instructions in a processor for processing pack data for furnishing compatibility with existing software and hardware. SOLUTION: For executing both of a set of pack data instructions and a set of floating point instructions on contents, which are aliased partially at least and correspond to a plurality of tags, of a single logical register file, the set of pack data instructions are executed before execution of the set of floating point instructions. At a certain time between a start of execution of a first instruction in the set of pack data instructions and execution of a first instruction in the set of floating point instructions, a plurality of tags matching an alias register in at least a single logical register file are changed into a non-empty condition, and the tags determine whether the register in a signal logical register file is empty or not.

摘要： PROBLEM TO BE SOLVED: To propose a method and a device for a transition instruction to a register file. SOLUTION: A transition instruction marking the end of a block including a pack data instruction operated to data stored in a logic register is received. A register in a logic register file shows whether a plurality of tags related to the logic register file are empty or not by responding to execution of a scalar floating point instruction for changing the data included in the logic register file. The plurality of tags come to show empty in response to the transition instruction. COPYRIGHT: (C)2004,JPO

摘要： In one embodiment, a method of remote attestation for a special mode of operation. The method comprises storing an audit log within protected memory of a platform. The audit log is a listing of data representing each of a plurality of IsoX software modules loaded into the platform. The audit log is retrieved from the protected memory in response to receiving a remote attestation request from a remotely located platform. Then, the retrieved audit log is digitally signed to produce a digital signature for transfer to the remotely located platform.
