Loading device and program loading method

Abstract

The invention provides a loading device and a program loading method. The loading device comprises a connector, a programmable module, a dial switch and a loading socket. The connector is used for enabling the loading device to be connected with an upper computer, the loading socket is used for connecting the loading device with a lower computer, the dial switch is used for selecting a loading mode from a plurality of loading modes, and the programmable module is used for determining a connector side pin and a loading socket side pin corresponding to the loading mode according to a code value selected by the dial switch, obtaining a bus signal of the upper computer from the connector side pin corresponding to the loading mode, and transmitting the bus signal of the upper computer to the corresponding lower computer through the loading socket side pin corresponding to the loading mode. By means of the loading device and the program loading method, the operation complexity generated in the program loading process of different programmable devices can be simplified, and the loading efficiency of programs of the programmable devices can be improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a loader and a program loading method. Background technique [0002] In modern electronic products, it is often necessary to load hardware logic programs or microcodes to some programmable devices to realize the required functions. As the board integration becomes higher and higher, more and more programmable devices are used on the board. For different programmable devices, such as CPLD (Complex Programmable Logic Device, Complex Programmable Logic Device), FPGA (Field-Programmable Gate Array, Field Programmable Gate Array), EEPROM (Electrically Erasable Programmable Read-Only Memory, Electrically Erasable Programmable read-only memory) and other different types of programmable devices, or the same type of programmable devices produced by different manufacturers, such as CPLDs produced by different manufacturers, when it needs to be loaded with programs, different...
