High-frame-frequency format conversion method and circuit for high-resolution image data

The invention discloses a high-frame-frequency format conversion method for high-resolution image data, and the method comprises the steps: S101, obtaining two completely independent RAMs (Random Access Memory) as image data caches, and respectively serving as buffer regions; and S102, connecting the two RAMs with ping-pong logic respectively. And S103, inputting the image data into packet format conversion logic, and generating a control signal, an address signal and a data signal written into the RAM of the image data cache. And S104, the data sequence reading logic generates a control signal and an address signal for reading the RAM according to a driving time sequence requirement, and transmits the control signal and the address signal to the ping-pong logic. And S105, switching read-write operation functions of the two RAMs through ping-pong logic control. And S106, the ping-pong logic sends the switched image data to a data sequence reading logic, grouping and rearrangement of the image data are complet
