A data processing host includes a program running environment and a first isolation environment. The first isolation environment is isolated from the program running environment. The host operates in a non-secure mode in the program running environment, and operates in a secure mode in the first isolation environment. The program running environment includes a virtual instance operating in the non-secure mode, and the first isolation environment corresponds to the virtual instance in the program running environment. The first isolation environment includes an operating system in the secure mode and a resource allocated to the first isolation environment and comprising a first isolation space for running the operation system and a secure processing program, which corresponds to a program in the virtual instance and is for processing to-be-processed data.

Data processing methods and apparatus switchable between secure and non-secure environments

A field effect transistor and a preparation method thereof, and a semiconductor structure are provided. An example field effect transistor includes: a substrate structure, a source, a drain, and a gate. The source and the drain are arranged on the substrate structure in a first direction, and a channel region is formed between the source and the drain. A channel layer is formed in the channel region, and N carbon nanotubes extending in the first direction are embedded in the channel layer, where N is an integer greater than or equal to 1. Two ends of each of the N carbon nanotubes are respectively connected to the source and the drain to form a conductive path. The gate is formed on the channel layer. In the channel region between the source and the drain, electron conduction is implemented by using the carbon nanotube disposed in the channel layer.

Field effect transistor and preparation method thereof, and semiconductor structure

A data processing system includes a computing subsystem and a memory subsystem. In the computing subsystem, a processor is connected to one end of a high-speed parallel bus via a first bus interface. The processor transmits data to the memory subsystem and receives data transmitted through the high-speed parallel bus. The memory subsystem receives and transmits data to the computing subsystem through the high-speed parallel bus.

Data processing system and method

Example error correction methods and apparatus are described. In one example method, a register controller detects an error existing in a memory, and after detecting an uncorrected error (UCE), obtains a memory address in which the UCE occurs. The register controller reads raw data from a location indicated by the memory address, stores preset first data in the location indicated by the memory address, and reads second data from the location after storing the first data in the location. The register controller compares the first data with the second data to determine a first failure location in the location, determines raw data stored in the first failure location from the raw data in the location, and performs error correction on the raw data stored in the first failure location.
