INFORMATION PROCESSING DEVICE AND INFORMATION PROCESSING METHOD

摘要

When a packet such as a control instruction requiring a real time execution is received in a computer in which a general-purpose OS is operating, it is impossible to guarantee a temporal constriction posed on the real time processing. As shown in Fig. 1, a computer component (104) which has received a packet from a network (101) judges whether the packet is to be transferred in real time by using a user logic IC (114). If the packet is to be transferred in a real time, a priority queue of a communication buffer (116) is selected and the packet is immediately transferred to other computer component (104) which can perform a real time process. Simultaneously with this, interrupt signal lines (126, 118) are asserted so as to report an interrupt signal indicating a real time transfer.
