<P>PROBLEM TO BE SOLVED: To make it possible to realize saving data at the time of normal operation without requiring a complicated HW configuration and with hardly deteriorating processing speed by effectively utilizing a vacant parallel processing section in a parallel processor. <P>SOLUTION: Since data of a memory can be rewritten by an FW process 4, the data before rewrite and an address at that time are saved in preceding FW processes 2 and 3. These saving processes are performed by a vacant processing unit in parallel processing. In FW processes (1)-(3), processing from the FW process 1 which is a rewrite preparation process preceding to the FW process 4 is retried by storing the restoration data in a restoration destination address and at the same time, branching to the head of this SW instruction. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
