Abstract
PURPOSE: To realize a high-speed compression process within a process system comprising mainly the computers, by receiving the picture data along with the control word from the computers connected directly to each other via the bus and then returning the picture data to the computer after storing it as a compression data.
CONSTITUTION: The control part 6 of a compressing device receives the number of picture elements of a line plus the number of lines as the control words and then transfers the constitution of the picture element to be compressed to the compression part 4. At the same time, a control is given to the transfer of picture element data to the input buffer part 3, the start/stop of the compression process at the part 4 and the transfer when the counted 7 compression data is returned to the computer memory from the output buffer 5 respectively. For the computer, the data is transferred to the DMA from the memory just by sending the transfer start command of both the picture element data and the compression data to the compressing device. The data is then returned to the memory after compressed by the exclusive hardware. As a result, an easy and high-speed process of compression is possible like a use of the subroutine in terms of the software of the computer.
