Abstract

The invention discloses a burning interface system, a microprocessor and a burning method, and the burning interface system comprises a burner state detection module which is used for receiving a power-on reset signal sent by a processor core of the microprocessor, determining the communication state of a burner and the burning interface system, and outputting a first multiplexing selection signal according to the communication state; the port multiplexing unit is used for selecting one of the burning data output end and the multiplexing output end to output data information according to the first multiplexing selection signal; the universal serial bus interface module is used for carrying out data communication with a burner; the main controller module is used for determining a decryption state of the memory according to the data information and executing a burning step control strategy on the memory according to the decryption state; and the memory driving module is used for executing the burning step control strategy on the memory so as to complete burning of the memory. By means of the programming interface system, chip port multiplexing can be achieved, and the problems that the programming process is complex, the speed is low and the hardware cost is high are solved.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a programming interface system, a microprocessor and a programming method. Background technique [0002] Non-volatile memory, such as flash memory, has been widely used in various processor chips because of its excellent characteristics of not losing data after power failure. The current programming method for non-volatile processors can be divided into two types of technologies. The first is to connect the JTAG interface of the chip and the emulator, and to use the corresponding host computer to update the non-volatile memory inside the chip. For programming, this method increases the cost and difficulty of research and development. The chip needs to integrate the JTAG interface, which also increases the complexity of chip design. The programming speed of non-volatile memory for a large number of chips is slow, and programming higher cost. The second is to use ...
