Ring-buffer based buffering apparatus and method of using memory apparatus

摘要

In a buffering apparatus for digital data for temporarily storing input data and then outputting, a memory apparatus is provided with a plurality of storage areas assigned consecutive identification numbers. A partition designation unit generates an instruction for partitioning the plurality of storage areas. An area partitioning unit partitions the plurality of storage areas in the memory apparatus at least into a first area and a second area in accordance with the generated instruction for partitioning and uses the first area as a buffer area, the first area including storage areas with consecutive identification numbers. A partition designation unit generates an instruction for partitioning that designates a border between the first area and the second area.
