A typical application programming scenario is shown in fig. 1; the burning is mainly divided into three parts: the system comprises burning software, communication equipment and a chip to be burned. The burning software generally runs on a PC, and the PC stores application programs and data which need to be burned to the chip. Generally, one burning PC host can be connected with a plurality of devices to be burned. The burning software sends the file to be burned to the chip on the device to be burned through the communication interface, and the program on the chip burns the file into the storage medium.
The traditional scheme for solving the problem of slow burning speed is to improve the communication speed in the burning process; however, in a factory burning environment, one burning host is connected with a plurality of devices to be burned, various electromagnetic interference problems exist, and the space for improving the communication speed is limited. And the communication speed is greatly improved, higher requirements are required for matching of burning hardware connection in a factory burning environment, and the production cost can be indirectly increased. In addition, the problem of the burning speed cannot be thoroughly solved due to the fact that the capacity of an internal memory in a product is far smaller than that of a storage medium, so that burning software cannot transmit data to be burned at one time, the data must be transmitted for multiple times, the transmission needs to wait for the data to be transmitted last time and be burned, the next data transmission and burning can be carried out only after the data is burned last time, and flow control communication needs to be carried out between the burning software and a device to be burned, so that the burning reliability can be guaranteed. The back-and-forth flow control communication between the burning software and the burned device also increases the extra burning time.
In view of the above, there is a need to design a new data recording method to overcome at least some of the above-mentioned defects of the existing data recording method.
