发明名称 Printer controller and system having a DMA data transmission
摘要 A printer controller and system that include a descriptor storing device which stores descriptor information, an image memory which stores at least one of encoded image data and non-encoded image data, a decoding device which decodes encoded image data, a first data path which transmits the encoded image data stored in the image memory to an external device via the decoding device, and a second data path which transmits the non-encoded image data stored in the image memory to the external device. The printer controller and system further include a direct memory access (DMA) control device that controls the image data stored in the image memory so as to be transmitted via one of the first data path and the second data path according to the descriptor information stored in the descriptor storing device.
