System and method applied in programming unit to realize intelligent switching of programmed chip timing

Abstract

The invention provides a system and a method applied in a programming unit to realize intelligent switching of programmed chip timing. The method includes: establishing a dynamic timing database at a PC end, and storing the model information of various model chips and the corresponding timing data therein; powering up the programming unit, and establishing communication connection with the PC end; letting a user to select the model information of a to-be-programmed chip through an external interface of the PC end, making the timing database at the PC end automatically match and select corresponding timing data according to the model information, then sending corresponding configuration commands and configuration information to the programming unit end; and performing hardware configuration by the programming unit end after receiving the configuration commands and configuration information. With the system and the method provided by the invention, the flexible programmed chip switching function, compatibility and scalability of the programming unit can be realized.

Description

technical field [0001] The invention relates to the field of integrated circuit programming, in particular to a system and method for intelligently switching and programming chip timings applied to a programmer. Background technique [0002] At present, in order to realize the programmer of each series of chips, the programming hardware needs to be changed frequently, which is very costly, and the hardware maintenance cost is unpredictable. In the development of the traditional burner platform, on the one hand, a huge circuit structure for storing timings is required to meet the timing storage of various chips, and the hardware cost is very high; How to burn the newly released chips requires engineers to modify the hardware storage circuit and maintain the hardware in the later stage; on the other hand, when adding new chips, traditional programming hardware cannot burn new chips, because Most engineers only develop corresponding programmers for the current chip, without co...

Problems solved by technology

In the development of the traditional programmer platform, on the one hand, a huge circuit structure for storing timings is required to meet the timing storage of various chips, and the hardware cost is very high; How to realize the programming of newly launched chips requires engineers to modify the hardware storage circuit and maintain the hardware in the later stage; on the other hand, when adding new chips, traditional programming hardware cannot burn new chips, this is because Most engineers only develop corresponding programmers for the current chips, without considering the upgrading of later products. When new products are produced in the later stage, they can only eliminate the old programmers or re-update the hardware programmers.

Obviously, the traditional programmer has obvious limitations, delaying the launch of the company's products, causing disadvantages to the company's development, and seriously affecting the promotion time of product solutions. On the basis of changing, realize the intelligent switching chip programming function of the programmer
