Background With the increasing demand for image display, in order to reduce the bandwidth of SoC (System on Chip) of multimedia devices (such as smartphones, tv set top boxes, and intelligent cabins), data sources are generally compressed into compressed data blocks and then stored, so that the compressed data blocks need to be taken out from the memory, scanned line by line, and output, so as to realize real-time image display. In the conventional technology, in order to ensure continuous output of a scanning result, ping-pong control is performed on 2 SRAMs (Static Random-Access memories) supporting storage of compressed data blocks, that is, image data obtained by decompressing a compressed data block stored in one of the SRAMs is scanned and output until all the stored images obtained by decompressing are scanned, a new compressed data block is read again, the image data obtained by decompressing the new compressed data block is written into the SRAM, and image data obtained by decompressing the compressed data block stored in the other SRAM is scanned and output, so that the cycle is performed until image display is completed. However, in the above conventional techniques, the required storage space of the SRAM is larger, and as the horizontal resolution of the displayed image is continuously increased, the demand for the storage space of the SRAM is also increased, which results in a larger occupied area of the SRAM for the display controller and affects the performance of the display controller.
