Problems solved by technology

Therefore, this type of microcontroller can only be programmed once. Even if the user's program code bytes are very small, it only takes up a small part of the OTP memory, and the rest cannot be used again, resulting in waste.

Abstract

The invention discloses an OTP (one time programmable) single chip microcomputer framework and a method for realizing multi-time programming. An offset address storage area is reserved in a program storage in the OTP single chip microcomputer. Every time the single chip microcomputer is programmed, an end address of programming of this time is written in the storage area after being added 1. When the single chip microcomputer is reset, an offset address reading module reads data from the area. By the single chip microcomputer framework and the method for realizing multi-time programming, the program storage of the single chip microcomputer can be used for many times without influencing normal operation of the single chip microcomputer, multi-time programming can be realized, and using efficiency of the single chip microcomputer can be improved.

Description

technical field [0001] The invention relates to the field of single-chip microcomputers, specifically the internal structure of the OTP single-chip microcomputer and the realization method of multiple programming. Background technique [0002] OTP single-chip microcomputer is widely used in various electronic products due to its stable performance and low price. In the traditional MCU architecture, such as figure 1 As shown, the processor core stores the program through the instruction address, and the working process of the single-chip microcomputer is as follows for each programming. [0003] 1. Power on the system. [0004] 2. The instruction address is reset to 0, and the processor core starts to work. [0005] 3. The processor core executes the instruction stored at address 0, and generates the next instruction address. [0006] 4. The processor executes the instruction stored in the instruction address generated in the previous cycle, and continues to generate the ...
