Abstract

The invention relates to an embedded multimedia LED display screen control system, comprising a single board hardware circuit which comprises a program memory, an application data memory, a high-speed memory, a CPU, a safety encrypting protection module, an ultra-large scale field programmable gate array (FPGA) integrated circuit, a high-speed upper screen time-sequence separation driving module, a large-capacity high-speed display memory, a high fidelity solid audio stream output module, a network driving interface, a USB extension interface, a serial driving interface, a clock calendar management module, and a high-class power management module. The embedded multimedia LED display screen control system employs mature and advanced 32-bit SOC (system on chip) high-speed processor and millions of ultra-large scale programmable integrated circuit FPGA as LED display scanning time-sequence signal generators, uses Linux real-time multi-task operation system with open sound code as for software to integrate electrons, software, memory, communication, graphs and images, audio / video decoding, and the like into a whole, and brings qualitative leap for the LED display system.

Description

technical field [0001] The invention relates to LED display screen control technology, in particular to an embedded multimedia LED display screen control system. Background technique [0002] LED: semiconductor light-emitting diode, widely used in the working status indication of many electrical appliances, the light emitted mainly includes red, green, blue, yellow, and white; LED unit board: a fixed-sized dot matrix module composed of LEDs, usually with different width and height It is composed of 8×8, 16×8, 16×16, 32×32, 64×32 and other pixel modules, which can adapt to any screen size; there are single-color, two-color and full-color screens; LED display: use The LED unit boards are spliced ​​into the size that needs to be displayed to display various texts, pictures, videos and other information. The outstanding feature that is different from LCD (liquid crystal) or CRT (picture tube) TV is that it can display large size and high brightness. It is usually used for Infor...
