Abstract
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).

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
117 words
A system for transferring data from an image acquisition device to a mainframe computer comprising: memory means for temporarily storing data received from the image acquisition device prior to transfer to the mainframe computer; means connected to the image acquisition device for generating blocks of data; a direct memory access controller interconnected between the image acquisition device and said memory for controlling the transfer of said blocks of data from the image acquisition device to said memory; means for controlling said direct memory access controller for partitioning said blocks of data into smaller sized blocks prior to transfer and storage in said memory means; and means for transferring said stored blocks of data to the mainframe computer.
Claim 2
Independent Claim
117 words
A system for transferring data from an image acquisition device to a mainframe computer comprising: memory means for temporarily storing data received from the image acquisition device prior to transfer to the mainframe computer; means connected to the image acquisition device for generating blocks of data; a direct memory access controller interconnected between the image acquisition device and said memory for controlling the transfer of said blocks of data from the image acquisition device to said memory; means for controlling said direct memory access controller for partitioning said blocks of data into smaller sized blocks prior to transfer and storage in said memory means; and means for transferring said stored blocks of data to the mainframe computer.
Claim 3
Independent Claim
68 words
A method for transferring data from an image acquisition device to a mainframe computer including the steps of: temporarily storing data received from the image acquisition device; transferring blocks of data from the image acquisition device to a direct memory access controller; partitioning said blocks of data into smaller size blocks; storing the data in said smaller sized blocks; and transferring said stored data to the mainframe computer.
Claim 4
Independent Claim
