IMAGE DATA TRANSMISSION APPARATUS OF PRINTER

摘要

a DMAC(60) for controlling transmission of video data according to a transmission request signal; a memory(110) for storing the video data; a video address selector(100) for receiving addresses through a system bus and separating the addresses of the memory corresponding to a transmission response signal applied from the DMAC; buffers(90,91) for separately buffering the data of the memory and data of the system bus in response to a specific address of the CPU(70); and a data size controller(80) for receiving a specific address and control signal through the system bus to control the size of the video data of the memory and buffer.
