Universal programmor and programming method

Abstract

A universal programmer is prepared as storing program codes of multiple object chip and driving program of a Ethernet chip in master control chip by said programmer, receiving and analyzing data by master chip through network interface, finalizing relevant upgrade according upgrade data packet (UDP) when analyzed data is UDP, programming program code of object chip requiring to be programmed to programming element according to programming command and controlling said element to generate control time sequence to finalize programming on object chip when analyzed data is programming data.

Description

technical field [0001] The invention relates to a programmer and its programming method, in particular to a universal programmer and its programming method. Background technique [0002] In the development and design of the hardware system, the data read and write operations on the chip are called chip programming (Program). For example, various systems controlled by a single-chip microcomputer (Single Processor) need a single-chip microcomputer to program the developed control program; program a chip for storing configuration data; ArrayDevices, FPGA Devices) or Complex Programmable Logic Devices (Complex Programmable LogicDevices, CPLD) programming. Although chip manufacturers can provide corresponding programming means for each component, there is an urgent need for a programming device that can support multiple different types of chips at the same time, so a universal programmer has become the first choice. [0003] Please refer to FIG. 1 , which shows a structural blo...

Problems solved by technology

However, this method also needs to be completed by the manufacturer, which brings great inconvenience to the user.

Moreover, the use of programmable read-only memory also brings hidden dangers to the security of the program code, because as long as the program code in the programmable read-only memory can be read or copied and placed in other field programmable gate array elements , other field programmable gate array components also have the same programming function, so there is a great potential safety hazard

[0005] In addition, the above-mentioned general-purpose programmers all have the characteristics of local programming of the chip, that is, the programming equipment can only realize the programming operation of the chip by operating the control program on the computer after the operator changes the chip, and cannot realize the remote control of the chip programming. Purpose

However, with the continuous expansion of production scale, the number and types of chips that need to be programmed are increasing. Simply relying on manual programming of chips has disadvantages such as low efficiency and high error rate. Therefore, it is necessary to realize the control of the universal programmer through automatic equipment. , so as to complete the programming of the production line chip
