Problems solved by technology
[0003] However, the inventors found that the existing technical solutions have the following problems: to transfer the entire program file from the PC to the program storage area of the chip, many transfers are required, which makes the entire download process time-consuming, which in turn leads to production efficiency. lower
For example: if the storage capacity of the chip’s program memory is 384Kbytes, the maximum amount of data to be transferred is 384KBytes. If 128Bytes are transferred each time, a total of 3072 transfers are required. If each transfer takes about 191ms, the entire download process takes about 10 minutes

Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0030] Such as figure 1 As shown, it is a schematic flowchart of a method embodiment of sending a program file for a chip according to the present invention. The method is executed on the PC side, and the method may include the following steps:
[0031] Step 11, read the program file that needs to be downloaded and parse the program file to form a data array;
[0032] Wherein, the program file includes code information and the address information of the non-volatile program memory storing the code information in the chip, for example: the program file is a HEX file, and the data array is code information arranged in order according to the address information;
[0033] Step 12, dividing the data array into data blocks of a predetermined size;
[0034] Step 13, compressing the data block, and sending the compressed data block to the chip;
[0...

The invention relates to a method and a device for downloading program files applied to chips. The method includes reading the program files required to be downloaded and analyzing the same to form a data array, dividing the data array into data blocks in preset size, and compressing the data blocks and sending the compressed data blocks to the chips. The program files include code information and address information of nonvolatile program memory, saving the code information, of the chips; the data array include the code information arranged according to the address information sequentially. By the method and the device, time for downloading the program files for the chips can be shortened and production efficiency can be improved.
Description
technical field [0001] The invention relates to the field, in particular to a method and device for downloading program files for chips. Background technique [0002] During the chip design process, in many cases, it is necessary to download program files from a personal computer (Personal Computer, PC for short) to the chip. The following uses the smart card chip as an example to introduce the whole process: on the PC side, the PC reads the program file to be downloaded. Since the amount of data transmitted each time is limited, the program file is transmitted to the reader in multiple times; the card reader Then the program file is sent to the smart card chip. At the chip end, the memory of the chip receives the program file sent by the card reader multiple times and writes the program file into the program memory. [0003] However, the inventor found that the existing technical solution has the following problems: to transfer the entire program file from the PC to the pr...
