A method includes, in response to a memory error indication indicating an uncorrectable error in a faulted segment, associating in a remapping table the faulted segment with a patch segment in a patch memory region, and in response to receiving from a processor a memory access request directed to the faulted segment, servicing the memory access request from the patch segment by performing the requested memory access at the patch segment based on a patch segment address identifying the location of the patch segment. The patch segment address is determined from the remapping table and corresponds to a requested memory address specified by the memory access request.

A vehicle communication system includes a switching hub incorporated in a vehicle and including a switch IC and an external CPU. The switch IC includes an internal CPU and performs a transfer process of transferring information to a communication device. The external CPU is provided outside the switch IC and connected to the switch IC, and has higher information processing capability than the internal CPU. The external CPU can perform a transfer order process of ordering to transfer information to the communication device and perform a security process of securing the security of the information to be transferred when the transfer order process is performed. The internal CPU monitors the operation of the external CPU and when the external CPU is abnormal, performs the transfer order process instead of the external CPU.

A method, computer program product, and computing system for operating an autonomous vehicle; monitoring the operation of a plurality of computing devices within the autonomous vehicle; and in response to detecting the failure of one or more of the plurality of computing devices, switching the autonomous vehicle from a nominal autonomous operational mode to a degraded autonomous operational mode.

Various embodiments may include methods and systems for reconfiguring memory channel routing within a system-on-a-chip (SoC). A method may include obtaining first error information in response to misbehavior in a first memory channel communicatively connected to a network interface unit (NIU) of the SoC. The method may further include storing the first error information in non-volatile memory that is read upon booting of the SoC, and rebooting the SoC including the first memory channel. The method may further include configuring the first memory channel to be communicatively disconnected from the NIU and configuring a second memory channel to be communicatively connected to the NIU in response to reading the stored first error information during reboot.

The method can include: identifying a storage device fault associated with a fault-resilient storage device; determining that a first region associated with the fault-resilient storage device comprises an inaccessible space and that a second region associated with the fault-resilient storage device comprises an accessible space; identifying a read command at the second storage device for the data and determine, based on the read command, first data requested by a read operation from a local memory of the second storage device; determining, based on the read command, second data requested by the read operation from the second region; retrieving the second data from the second region; and scheduling a transmission of the second data from the fault-resilient storage device to the second storage device.

A vehicular control system includes a plurality of electronic control units (ECUs), each providing a respective quantity of computational units representative of an amount of processing power of the respective ECU. The ECUs operate a vehicle in a nominal autonomous operational mode when a sum of the quantity of computational units exceeds a threshold. The system, while the ECUs operate the vehicle in the nominal autonomous operational mode, and responsive to detecting a failure of one of the ECUs, determines whether a sum of the quantity of computational units of the remaining ECUs that do not have a failure exceeds the threshold. The ECUs, responsive to the system determining that the sum of the quantity of computational units of the remaining ECUs fails to exceed the threshold, switches from operating the vehicle in the nominal autonomous operational mode to operating the vehicle in a degraded autonomous operational mode.

A storage device with improved security performance is provided. The storage device comprises a first non-volatile memory storing a firmware image, a second non-volatile memory storing an emergency image, and a storage controller controlling the first and second non-volatile memories, wherein the storage controller checks an integrity of the firmware image received from the first non-volatile memory, loads and executes the emergency image from the second non-volatile memory when the integrity check of the firmware image fails, receives a recover image from an external device based on the emergency image, and provides the recover image to the first non-volatile memory.

A data processing system includes a system interconnect, a first master, and a bridge circuit. The bridge circuit is coupled between the first master and the system interconnect. The bridge circuit is configured to, in response to occurrence of an error in the first master, isolate the first master from the system interconnect, wherein the isolating by the bridge circuit is performed while the first master has one or more outstanding issued write commands to the system interconnect which have not been completed. The bridge circuit is further configured to, after isolating the first master from the system interconnect, complete the one or more outstanding issued write commands while the first master remains isolated from the system interconnect.

A memory system includes a plurality of volatile memory modules to temporarily store data in a distributed manner, a V storing place management unit included in each of the volatile memory modules, a plurality of nonvolatile memory modules to store the data stored in each of the volatile memory modules in a distributed manner, and a NV storing place management unit included in each of the nonvolatile memory modules. Each V storing place management unit and each NV storing place management unit communicate and determine the destination nonvolatile memory module for each volatile memory module. The data is transmitted to the determined destination nonvolatile memory module and stored in the destination nonvolatile memory module.

A method of operating a storage device may include determining a fault condition of the storage device, selecting a fault resilient mode based on the fault condition of the storage device, and operating the storage device in the selected fault resilient mode. The selected fault resilient mode may include one of a power cycle mode, a reformat mode, a reduced capacity read-only mode, a reduced capacity mode, a reduced performance mode, a read-only mode, a partial read-only mode, a temporary read-only mode, a temporary partial read-only mode, or a vulnerable mode. The storage device may be configured to perform a namespace capacity management command received from the host. The namespace capacity management command may include a resize subcommand and/or a zero-size namespace subcommand. The storage device may report the selected fault resilient mode to a host.
