A processor implementing an improved method for executing load instructions includes execution circuitry, a plurality of registers, and instruction processing circuitry. The instruction processing circuitry fetches a load instruction and a preceding instruction that precedes the load instruction in program order, and in response to detecting the load instruction, translates the load instruction into separately executable prefetch and register operations. The execution circuitry performs at least the prefetch operation out-of-order with respect to the preceding instruction to prefetch data into the processor and subsequently separately executes the register operation to place the data into a register specified by the load instruction. In an embodiment in which the processor is an in-order machine, the register operation is performed in-order with respect to the preceding instruction.

A memory sharing method of virtual machines through the combination of KSM and pass-through, including: a virtual machine manager judging whether operating systems of guests use IOMMU, if not, not participating in shared mapping of a KSM technology; if yes, judging memory pages of each guest to confirm whether the pages are mapping pages, if yes, remain the mapping pages into a host; and if not, on the premise of keeping the properties of Pass-through, using the KSM technology for all non-mapping pages to merge the memory pages with same contents among various virtual machines and perform write protection processing simultaneously. The guest memory pages are divided into those special for DMA and those for non-DMA purpose, then the KSM technology is only selectively applied to the non-DMA pages, and on the premise of keeping the properties of Pass-through, the object of saving memory resources is achieved simultaneously.

The present invention provides a light source control module, a backlight module and driving method thereof which can overcome the problems of insufficient color amount, poor performance and lowered color saturation. A light source control module of the present invention is used for separately controlling illumination colors and/or brightness of each light source in the backlight module according to image information. The driving method of the backlight module comprises: calculating representative color and/or brightness of each image section based on image information, wherein each image section corresponds to a light output area on the output surface of the backlight module, each light output area is illuminated by one light source in the backlight module; adjusting the illumination colors and/or brightness of each light source such that the color and/or brightness of each light output area is in conformity with the representative color and/or brightness of corresponding image section.

A monomer for use in manufacturing a conjugated polymer, the monomer having a structure as shown formula (2):

Ar₁, Ar₂ and Ar₃ are independently selected from optionally substituted aryl or heteroaryl, X₁ and X₃ both independently comprise a leaving group capable of participating in polymerisation and Z represents a direct bond or an optionally substituted bridging atom.

The invention discloses a modified rice hull ash-silicone rubber composite material which consists of 107 base rubber, a cross-linking agent, a chain expander, modified rice hull ash, a catalyst, a plasticizer and an adhesive, wherein the modified rice hull ash is prepared by: 1) performing acid pickling pretreatment on rice hulls before calcining; 2) calcining the pretreated rice hulls at low temperature and high temperature in sequence; and 3) grinding, grading and performing surface treatment on the calcined rice hull ash. The invention further discloses a preparation method of the composite material. The rice hull ash prepared by using the method disclosed by the invention in a modification manner can be relatively well used for preparing the modified rice hull ash-silicone rubber composite material, and moreover, the prepared composite material is low in modulus, good in elongation performance and good in self-leveling property, and can be widely used in the fields of traffic and buildings.

The invention discloses a water-soluble electrolyte system and application of a water-soluble electrolyte system in an electrochemical oxygen sensor, relates to electrolyte and application thereof and aims to solve the problem of sensor failure caused by easy water volatilization in the existing electrolyte system. The water-soluble electrolyte system consists of an electrolyte material and a support material, wherein the electrolyte material is water; the support material is hydrophilic ionic liquid; the hydrophilic ionic liquid is placed in the environment with a certain humidity and the water is naturally absorbed until the hydrophilic ionic liquid is constant in weight so as to obtain the water-soluble electrolyte system. The invention also discloses application of the water-soluble electrolyte system which is used as electrolyte in the electrochemical oxygen sensor. The water-soluble electrolyte system has the advantages that the water electrolyte material is absorbed and maintained by using the relatively strong water absorption property of the hydrophilic ionic liquid, so that the problems of poor performance and short service life of the sensor caused by volatilization of the water electrolyte can be avoided.
