Abstract

The invention proposes a method of buffering for multi-stream, wherein, the read operation and write operation share one common buffer, the method comprises: I. performing read operation on the buffer to flush the content in a part of the addresses of the buffer; II. writing data into the part of addresses that have been flushed.
