COMMUNICATION PROCESSING CIRCUIT AND COMMUNICATION PROCESSING METHOD |
摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a communication processing circuit capable of transferring a packet which must be transferred to a CPU out of received packets to the CPU without discarding it. <P>SOLUTION: The communication processing circuit is provided with a plurality of queues 73-1 to 73-N. A frame analyzer 31 and a frame search 41 detect frame information of a frame as a target to be input into the CPU from among the frames to be received. A queue input 60 selects the queues 73-1 to 73-N having priorities corresponding to information indicating a factor by which the frame information detected by a detecting means is a target input into the central processing circuit, and generates job information based on this frame information and inputs the generated information into the selected queues 73-1 to 73-N. A queue outputting section 80 orderly reads the job information from the plurality of queues 73-1 to 73-N in conformity with a predetermined queue reading regulation, and inputs the frame information corresponding to the read job information into the CPU. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
