The traditional LED electronic display control circuit is mainly designed by conventional digital circuit, which is generally controlled by digital circuit combination. In traditional technology, after the circuit design part is completed, the circuit board is made first, and the relevant components are installed and the effect is adjusted. When the circuit board logic function cannot meet the actual demand, it needs to be remade until it meets the use effect. It can be seen that the traditional design method not only has a certain degree of contingency in effect, but also has a long design cycle, which affects the effective development of various processes. When components fail, maintenance is difficult and the cost is high.
On this basis, system programmable technology (ISP) appeared, users can have the function of repeatedly modifying their own design goals and the system or circuit board and other components, realizing the process of designers' hardware program to software program, digital system on the basis of system programmable technology take on a new look. With the introduction of system programmable technology, not only the design cycle is shortened, but also the use of components is radically expanded, field maintenance and target equipment functions are simplified. An important feature of system programmable technology is that it does not need to consider whether the selected device has any influence when using system software to input logic. During input, components can be selected at will, and even virtual components can be selected. After input is completed, adaptation can be carried out.
