Abstract

PURPOSE: To open buffers efficiently by causing a request originating module to indicate that buffer open is available in respect to individual contents of queued buffers and to request the processing to an execution module.
CONSTITUTION: #0 to #3 data are prepared in data buffer pool 4 by request originating #0 module 2-0. Start addresses A-1 of buffer queue managenment table 3 is set in pointer 6 of the #0 module. The start address of each buffer, the address of a queue state, and buffer open indication flag × are set in table 3. The #0 module transfers contents of the pointer to execution #1 module 2-1 and requests the transmission of data. The #1 module opens the buffer of flag × on a basis of table 3 and transmits data of another buffer. The #0 module indexes the table on a basis of pointer 6 and opens the buffer after collation of data, and the buffer is utilized for another processing. As a result, the buffer is not restricted for a long time.
