System on chip supporting multi-screen display, synchronization method for multi-screen display, and electronic device

A synchronization method for multi-screen display based on a system on chip, characterized by comprising:

• performing, by a processor core, a write operation on a synchronization control register of a timing generator corresponding to a display screen performing multi-screen display, to enable a display synchronization function of the timing generator, and divide the timing generator into a master timing generator and a slave timing generator;
• generating, by the master timing generator, a first timing synchronization signal, transmitting the first timing synchronization signal to a display screen corresponding to the master timing generator, and transmitting a vertical synchronization signal of the first timing synchronization signal to the slave timing generator;
• and
• generating, by the slave timing generator, a second timing synchronization signal in response to the vertical synchronization signal transmitted by the master timing generator, and transmitting the second timing synchronization signal to a display screen corresponding to the slave timing generator.

An electronic device, comprising a display screen and the system on chip supporting multi-screen display,

• wherein the display screen is configured to perform multi-screen display based on a first timing synchronization signal output from a master timing generator and a second timing synchronization signal output from a slave timing generator in the system on chip;
• wherein the system on chip supporting multi-screen display comprises:
• a processor core configured to perform a write operation on a synchronization control register of a timing generator corresponding to a display screen performing multi-screen display, to enable a display synchronization function of the timing generator, and divide the timing generator into a master timing generator or a slave timing generator;
• wherein
• the master timing generator is configured to generate a first timing synchronization signal, transmit the first timing synchronization signal to a display screen corresponding to the master timing generator, and transmit a vertical synchronization signal of the first timing synchronization signal to the slave timing generator;
• and
• the slave timing generator is configured to generate a second timing synchronization signal in response to the vertical synchronization signal transmitted by the master timing generator, and transmit the second timing synchronization signal to a display screen corresponding to the slave timing generator.
