    Abstract: A system for model protection includes a processor. The processor is arranged to execute a guest virtual machine (VM), a primary VM, and a hypervisor. The guest VM includes a model, and is arranged to send at least one command to a command hub. The primary VM is arranged to refer to the at least one command sent from the command hub to manage and configure a protection setting for a protected model derived from the model. The hypervisor is arranged to receive a safety setting command sent by the primary VM, and manage and configure the safety protection component according to the safety setting command, to set a read-only mode of the protected model.

    Abstract: A system for kernel protection includes a processor and a transmission interface. The processor is arranged to execute at least one guest virtual machine (VM), at least one primary VM, and a hypervisor. The at least one guest VM is arranged to send at least one command to a command hub. The at least one primary VM is arranged to manage and configure a safety setting according to the at least one command from the command hub and at least one policy, and manage and configure a safety protection component according to the safety setting. The hypervisor is arranged to manage and configure the safety protection component according to a ground rule and at least one safety setting command from the at least one primary VM. The transmission interface is arranged to bind the at least one primary VM to the hypervisor.

    IPC: G06F9/455

    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.

    Abstract: A controller and a memory-access method for use in the controller are provided. The controller includes a sensor-processing system, and the sensor-processing system includes a memory, and a buffer, wherein the controller is coupled to an external memory and a sensor. The method includes the steps of: gathering the sensor data from the sensor and writing the gathered sensor data into the memory; writing information associated with the sensor data into the buffer; determining whether a fill level of the buffer has reached a predetermined threshold; and retrieving the sensor data from the memory and writing the retrieved sensor data to the external memory according to the information associated with the stored sensor data in the buffer when it is determined that the fill level has reached the predetermined threshold.
