Embodiment Construction

[0039] As shown in Figure 2, a general-purpose chip software loader includes:

[0040] The interface socket 23 is used for plugging in the loading line and connecting with the background computer 1 through the loading line to realize bidirectional data transmission between each other. The interface socket 23 can be, but not limited to, a parallel port socket, a network port socket, a port socket or a USB socket;

[0041] The control and drive module 22 is a logic gate array chip and its auxiliary circuits, which are used to realize the mapping function of different signal pins of the interface socket 23, and connect the signal lines with the same function from the different pins of the interface socket 23 to On the same functional module as the control drive module, and control the power distribution module 21;

[0042] The board connection line 28 is used to connect the control and drive module 22 with the chip application board 3 to realize bidirectional data transmission b...

Abstract

It's a common software loader of chips, including: interface socket (23), control and drive modules (22), a hardware logic gate array chip and its subsidiary circuit for implementing the different signal-pin mapping functions of interface socket(23), connecting the same functional pin signal lines from the different interface sockets( 23) to the same function modules of the control module drives; Veneer wires (28), used to connect the control and drive modules (22) and the chip board (3), achieving two-way data transmission between them; Power points allocation Module (21), output the power signal from single wires (28)to power signal pins of the interface jacks (23)according the input control single from the control and drive modules (22). The invention meets the requirement that loading on a variety of programmable chip devices by a single loader, which lowers the costs and enhances connectivity flexibility.

Description

technical field [0001] The invention relates to a chip software loader, in particular to a general chip software loader capable of loading multiple different chips. Background technique [0002] The physical part of a loading tool currently used for chip software loading mainly includes a loading line and a loading head. The loading line is mainly used to connect the background computer and the loading head. One end of the loading head is connected to the loading line, and the other end is connected to the loading interface on the chip application board through a specially defined interface. The loading interface is then connected to the loading signal function pin of the specific chip through the wiring inside the printed circuit board. Most of the different chip manufacturers provide their own loading tools or provide their own detailed design schemes and entrust a third party to process and manufacture the loading tools. Since there are thousands of chip manufacturers,...
