초록
This paper proposes the self test method for 16 point FFT processor with systolic array architecture. To test efficiently and solve the increased hardware problems due to built-in self test, we change the normal registers into Linear Feedback Shift Registers(LFSR). LFSR can be served as a test pattern generator or a signature analyzer during self test operation, while LFSR a ordering register or a accumulator during normal operation. From the results of logic simulation for 16 point FFT processor by YSLOG, the total time is estimated in about. 21.4 [us].
