摘要： Techniques for using CPUID for showing features that are deprecated are described. In some examples, CPUID is to include at least one field for an opcode, one or more fields to identify a source operand which is to store a LSL selector value, and one or more fields to identify a destination register operand, wherein the opcode is to indicate that execution circuitry is to, when the single instruction has been enabled by a setting of a bit in a control register, write a LSL value stored in the control register to the destination operand when the LSL selector value of the first source register operand matches a LSL selector value stored in the control register, and set a flag in a flags register.

摘要： In one embodiment, fault information relating to a fault associated with the operation of guest software is received. Further, a determination is made as to whether the fault information satisfies one or more filtering criterion. If the determination is positive, control remains with the guest software and is not transferred to the virtual machine monitor (VMM).

摘要： A sample feeding device for a trace detector is disclosed. The sample feeding device comprises: a sample feeding chamber disposed in the sample feeding device to desorb a sample from a sample feeding member; and a valve assembly configured to fluidly communicate the sample feeding chamber with a drift tube of the trace detector during feeding sample. With the above configuration of the present invention, for example, the sensitivity of the detector can be increased by improving the permeation ratio of the sample. In addition, interior environment of the drift tube is isolated from exterior environment to avoid a drift region of the drift tube from being polluted. The important parameters, such as sensitivity, a position of a peak of a substance, a resolution, of the detector can be kept constant. As a result, operation reliability and consistency of the detector can be achieved.

摘要： Apparatus and method for injected spin echo sequences in a quantum processor. For example, one embodiment of a processor comprises a decoder to decode quantum instructions to generate quantum microoperations (uops) and non-quantum instructions to generate non-quantum uops; execution circuitry to execute the quantum uops and non-quantum uops; a corrective sequence data structure to identify and/or store corrective sets of uops for one or more of the quantum instructions; wherein the decoder is to query the corrective sequence data structure upon receiving a first quantum instruction to determine if one or more corrective uops exist and if the one or more corrective uops exist, then to submit the one or more corrective uops for execution by the execution circuitry.
