ABSTRACT:
A FIFO section having a FIFO memory is provided between a memory control section and a CPU_I/F section in a path through which image data outputted from a CPU is written into the video memory. Data necessary for writing the image data is stored into the FIFO section and, based on the data stored in the FIFO section, the image data is stored into the video memory under the control of the memory control section. With this configuration, the CPU can output the image data without a wait time until the FIFO memory becomes full, and thus there is provided a liquid crystal display control device that does not lower the operation efficiency of the CPU.
