摘要： An image processor is described. The image processor includes an I/O unit to read input image data from external memory for processing by the image processor and to write output image data from the image processor into the external memory. The I/O unit includes multiple logical channel units. Each logical channel unit is to form a logical channel between the external memory and a respective producing or consuming component within the image processor. Each logical channel unit is designed to utilize reformatting circuitry and addressing circuitry. The addressing circuitry is to control addressing schemes applied to the external memory and reformatting of image data between external memory and the respective producing or consuming component. The reformatting circuitry is to perform the reformatting.

摘要： A scanner having a synchronization dynamic random access memory and its memory access method. The scanner has an image processor for processing digital image signals, a SDRAM compensation memory unit for holding compensation data, a SDRAM image archiving memory unit for holding processed digital image data and an input/output device for connecting with an external device. A plurality of buffers couple the compensation memory unit with the image processor, the image processor with the image archiving memory unit and the image archiving memory unit with the input/output device.

摘要： Video data signals which are generated from a portable image scanner and temporarily stored in a shift register in an interface circuit are transferred to an external image processing device such as a word processor through a switching circuit which turns on upon reception of a transfer permission signal from a latching circuit for validating scanning condition. Since the transferring of the video data signals to the image processing device are effected without being controlled by the image processing device, it can be performed at high speed without causing a scanning error even if the sub-scanning speed is rather increased.
