Abstract

PURPOSE: To omit the program processing and thus increase the test velocity by transferring in a high speed only the corresponding file detected from the external memory part to the main memory part.
CONSTITUTION: Next file address 23 of file 22 in external memory circuit 19 is sent to the present file address storage part 8. And compared data 24 of file 22 is collated with the comparison data of the file index information transmitted from comparison data storage part 9 through comparator 17. When the cioncidence is secured with the corresponding file through the comparison, circuit 17 transmits the detection signal to transfer circuit 14. Circuit 14 reads out the transfer address to main memory 2 out of transfer address storage part 10 by receiving the detection signals, and then transfers all data of file 22 stored at file storage part 11 to the prescribed storage place in memory 2. And detection interruption is delivered to process circuit 1 after the transfer end process. Circuit 1 starts timing generation circuit 5 to continue the retrieval after arranging the file.
