Abstract
A system (10) for transferring data from an image acquisition device (12) to a mainframe computer (14) includes a memory (20) for temporarily storing data received from the image acquisition device (12) prior to transfer to the mainframe computer (14). A direct memory access controller (18) is interconnected between the image acquisition device (12) and the memory (20) for controlling the transfer of blocks of data from the image acquisition device (12) to the memory (20). Structure (30) is provided for controlling the direct memory access controller (18) for partitioning the blocks of data into smaller sized blocks prior to the transfer and storage of this data in the memory (20). Structure (32, 36) functions to transfer the stored blocks of data to the mainframe computer (14).
