摘要： PROBLEM TO BE SOLVED: To provide a buffer circuit with high efficiency of using a memory for a buffer, and to provide a buffer circuit control method.SOLUTION: The buffer circuit includes: a memory means for the buffer storing frame data; a storage-amount-for-each-attribute-value monitoring means for output of a storage amount for each attribute value indicating the number of the frame data stored in the memory means for the buffer for each attribute of the frame data; a storage decision means for calculating the upper limit amount of the storage amount for each attribute value on the basis of the free capacity of the memory means for the buffer or the storage amount or the increase and decrease, comparing the storage amount for each attribute value with the upper limit amount of the storage amount for each attribute value when the attribute value indicating the attribute of the frame data is input, determining whether to store the frame data of the attribute value in the memory means for the buffer, and for output of information indicating storage presence when storing them; and a memory-for-buffer control means for writing the frame data to the memory means for the buffer when the frame data is input and the information of the storage presence is input from the storage decision means.
