Trusted embedded computer based on godson processor and configuration method of trusted embedded computer

Abstract

The invention discloses a trusted embedded computer based on a godson processor and a configuration method of the trusted embedded computer. The configuration method comprises the following steps of transplanting a PMON as a BootLoader layer of a hardware system, so as to complete the starting configuration of a system, initializing of a register, and loading of an inner core, and realizing trusted operation; configuring and transplanting an open-source operation system into the hardware system, and managing and driving the whole hardware system. The configuration method has the advantages that a godson embedded microprocessor is used as a hardware platform, the open source embedded operation system is run, and a high-speed network communication technique and a TPM-based trusted computing technique are integrated, so as to realize a new generation of industrial control computer and industrial control system; the transmission of complicated network protocols and massive data and the running of relatively complicated control algorithms can be supported at high efficiency.

Description

technical field [0001] The invention belongs to the technical field of embedded computers, in particular to a trusted embedded computer based on a Godson processor and a configuration method. Background technique [0002] At present, industrial control computers at home and abroad are usually used in special industrial computers based on X86 processors and industrial computers based on 8 / 16-bit microcontrollers. The application status of these two types of industrial computers is as follows: [0003] 1. Dedicated industrial computer based on X86 processor: At the beginning of the fieldbus control system, due to the limitation of computer software and hardware technology, the control computer generally uses a special industrial computer based on X86 processor, but due to the system cost, function Due to the limitations of factors such as power consumption, volume and reliability, it cannot be applied to sensor nodes and actuator nodes.

Problems solved by technology

[0003] 1. Dedicated industrial computer based on X86 processor: At the beginning of the fieldbus control system, due to the limitation of computer software and hardware technology, the control computer generally uses a special industrial computer based on X86 processor, but due to the system cost, function Due to the limitations of factors such as power consumption, volume and reliability, it cannot be applied to sensor nodes and actuator nodes

[0004] 2. Industrial computer based on 8 / 16-bit microcontroller: It is better than the special industrial computer based on X86 processor in terms of system cost, power consumption and volume, but due to the limitation of the processing capacity of the microcontroller used and the To meet the increasingly complex control system requirements, the design of intelligent network nodes is becoming more and more complex, even using a multi-processor architecture, which makes this type of industrial computer costly and complex

Obviously, adopting this method to build the control node of the control system, no matter the complexity of the software and hardware of the system, or the reliability and realizability of the system, are not satisfactory; and the 8 / 16-bit microcontroller Computing and addressing capabilities are very limited

[0005] Therefore, the existing industrial control computers cannot efficiently support complex network protocols, the transmission of large amounts of data, and the operation of relatively complex control algorithms; and with the gradual development of networked control systems and the continuous improvement of control requirements, such Network nodes are increasingly unable to meet the needs of the system
