  • Publication number: 20230091722
    Abstract: A computing system includes a processor, and the processor is arranged to execute: a guest virtual machine (VM), a hypervisor, and a primary VM, wherein an operating system (OS) runs on the guest VM, and an application (APP) runs on the OS. The kernel of the OS includes a protection service module and a memory management unit (MMU) manager. The protection service module is arranged to receive at least one virtual address and a first size information sent by a client of the APP. The primary VM includes a protection manager, and the protection manager is arranged to obtain a physical address array and a second size information according to the at least one virtual address and the first size information sent by the protection service through the hypervisor.

  • Publication number: 20220382577
    Abstract: A system controls access to a physical address (PA) space. The system includes multiple system resources addressable within the PA space, and multiple processing circuits executing multiple virtual machines (VMs). A given region of the PA space is dedicated to addressing the VMs. The system also includes multiple memory management units (MMUs) coupled to corresponding processing circuits. A given MMU is operative to translate a virtual address indicated in an access request from a processing circuit into a requested PA that is accessible by the processing circuit according to a configurable setting of the given MMU. The system further includes multiple memory protection units (MPUs). A given MPU, which is coupled to a target system resource allocated with the requested PA, is operative to grant or deny the request based on information indicating whether the requested PA is accessible to a requesting VM executed on the processing circuit.

  • Patent number: 9645570
    Abstract: A monitoring system includes at least one light sensor, at least one fastener and at least one controller. The light sensor is configured to detect light emitted by an operation lamp. The fastener wraps around the operation lamp, and it includes a light-shielding body. The light-shielding body has an accommodation groove and an inner surface. The inner surface is adjacent to the operation lamp. The accommodation groove is concavely formed at the inner surface. The light sensor is accommodated in the accommodation groove. The controller is electrically connected with the light sensor for determining a status of the machine according to the light detected by the light sensor.

  • Patent number: 9552043
    Abstract: A handheld electronic device is provided. The handheld electronic device includes a touch display unit, a sensor unit and a processing unit. The sensor unit detects a rotation angle of the handheld electronic device relative to a gravity direction and a displacement of the handheld electronic device. The processing unit is electrically connected to the touch display unit and the sensor unit to extend a timeout threshold of the touch display unit from a first value to a second value that is larger than the first value when the rotation angle is within a reading mode range. The processing unit keeps the timeout threshold at the second value when at least a first condition that the displacement of the handheld electronic device is larger than a predetermined value is met.
