Abstract

The invention relates to an on-line upgrading technology of a single-chip microcomputer, and discloses a single-chip microcomputer on-line upgrading method, solving the problems of low upgrading efficiency and disadvantageous to prolonging the service life of the single-chip microcomputer existing in the on-line upgrading scheme of the prior art. The method comprises the following steps: acquiringcurrent mirror data and target mirror data of a single chip microcomputer; slicing the current mirror data and the target mirror data; comparing slices of the current mirror data and slices of the target mirror data sequentially and one by one, and sending slices of the target mirror data with difference to the non-execution area of the memory of the single chip microcomputer; copying the targetimage data stored in the non-execute area of the memory of the single chip microcomputer to the execute area in pieces. In addition, the invention also discloses a single-chip microcomputer on-line upgrading system, which is suitable for on-line upgrading of the single-chip microcomputer.

Description

technical field [0001] The invention relates to an online upgrading technology of a single-chip microcomputer, in particular to an online upgrading system and method of a single-chip microcomputer. Background technique [0002] At present, in electronic equipment, embedded systems using single-chip microcomputers as control processors are more and more widely used. The single-chip microcomputer mainly realizes various electronic device functions by running its internally stored image. Because in the actual application of the single-chip microcomputer, the mirror image needs to be continuously corrected according to the demand, so the single-chip microcomputer needs to be continuously upgraded. The manual upgrade method needs to rely on the programming environment, and it is troublesome to disassemble the device. Therefore, manufacturers or users prefer the more efficient online upgrade method. [0003] The patent application number 201410355659.9 discloses an online upgrad...
