In a computer system supporting execution of virtualization software and at least one instance of virtual system hardware, an interface is provided into the virtualization software to allow a program to directly define the access characteristics of its program data stored in physical memory. The technique includes providing data identifying memory pages and their access characteristics to the virtualization software which then derives the memory access characteristics from the specified data. Optionally, the program may also specify a pre-defined function to be performed upon the occurrence of a fault associated with access to an identified memory page. In this manner, programs operating both internal and external to the virtualization software can protect his memory pages, without intermediation by the operating system software.

The invention belongs to the technical field of vehicle maintenance and relates to a vehicle maintenance reminding system which includes a system hardware terminal that is arranged on the body of a vehicle and used for collecting parameter information relevant to the vehicle maintenance and storing the collected parameter information; a central information processing center which receives the parameter information relevant to the vehicle maintenance and stores the parameter information into a database, checks the change process of the received parameter information relevant to the vehicle maintenance, generates the information of the items and the dates of the vehicle maintenance and transmits the information by the Internet; and a system software terminal; the central information processing center transfers the information of the items and the dates of the vehicle maintenance generated by central information processing center to the system software terminal by the Internet and the system software terminal reminds a vehicle owner to carry out maintenance. The vehicle maintenance reminding system of the invention solves the existing technical problem that the actual maintenance time of the vehicle is misplaced with the time actually needed by the vehicle maintenance, namely, the forward maintenance or the hysteretic maintenance of the vehicle.

The invention discloses a motion controller which comprises a Core board, an MC board and a power supply module, wherein the Core board is mounted on the MC board in an insertion manner. The power supply module supplies corresponding voltages to the Core board and the MC board. The Core board comprises an ARM process, a memory module, a storage module and a data exchange module. The MC board comprises an FPGA, a DA module, a motor driving module and a signal input/output module. The motion controller aims at requirements of specific devices in different industrial fields. Only adjustment on the hardware of the MC board is required, and adjustment on the hardware of the Core board is not required. A development period of a product is shortened. Furthermore the ARM processor is utilized on the Core board. Because the ARM has peripheral resources such as USB, serial ports and network ports, outer expansion of a corresponding interface chip is not required, thereby simplifying hardware design and improving system hardware reliability.
