A high-security mimetic microprocessor device and data processing method

Abstract

The invention provides a high-safety and high-reliability mimic microprocessor device and a data processing method. The mimic microprocessor device comprises a scheduler and a plurality of heterogeneous micro-computing controllers which are respectively connected with the scheduler, The scheduler calculates the receiving rate of the controllers according to the plurality of heterogeneous microcomputers; and the data sent by the external device is distributed to the plurality of heterogeneous micro-computing controllers, operation results returned by the plurality of heterogeneous micro-computing controllers are received according to a preset transmission rate, mimicry judgment is carried out on the operation results according to the current working mode, and the operation results after judgment are output. The plurality of heterogeneous micro-computing controllers participate in operation at the same time, even if a few heterogeneous micro-computing controllers receive external attacksor generate internal vulnerabilities, normal work of the mimic microprocessor device can be ensured, and the correctness of output results is ensured, so that the reliability and the attack defense capability of the mimic microprocessor device are improved.

Description

technical field [0001] The present invention relates to the technical fields of microprocessing, microcomputing and microcontrol, in particular to a highly safe and highly reliable microprocessor device and data processing method, and proposes a Mimic Micro Computing Controller Unit (Mimic Micro ComputingController Unit) device and system Structure, working mechanism and data calculation and processing method, the mimetic microprocessor includes two main components: a heterogeneous micro-computing controller and a scheduler. Background technique [0002] Microprocessor Unit (Micro Processor Unit), also known as Single Chip Microcomputer (Single Chip Microcomputer) or single-chip microcomputer, is to appropriately reduce the frequency and specifications of the Central Processing Unit (Central Process Unit; CPU), and reduce the memory (memory), counter (Timer), USB (Universal Serial Bus, Universal Serial Bus), A / D (Analog / Digital) conversion, UART (Universal Asynchronous Recei...

AI Technical Summary

Problems solved by technology

[0003] At present, microprocessors are widely used and play a key control role in the circuit, but the reliability of a single microprocessor is poor, and it is likely that the calculation results will be wrong or invalid due to external attacks or internal loopholes.
