PROBLEM TO BE SOLVED: To solve the problem of the risk that product cost increases because the need of designing an intermediate buffer control mechanism in each number of faces of an intermediate buffer when attempting to create a common circuit for a plurality of products in which the number of faces of an intermediate buffer and writing and reading orders are different.SOLUTION: About a storage device provided with a plurality of storage areas, a writing order or a reading order of data to/from the storage areas is held in order to synchronize input/output control of the data in/from the storage areas, one storage area accessing the storage areas is selected along a holding order, and an intermediate buffer control mechanism can be applied to various intermediate buffers by executing synchronization control of input/out processing to/from the intermediate buffers. |
