HIGH SPEED SYNDROME CALCULATION METHOD AND SYNDROME CALCULATOR USING THE SAME

摘要

syndrome by reducing the number of clock cycles required during operation to compute the syndrome calculation Syndrome fast way and the syndrome calculator are disclosed. The syndrome calculation method at the same time that is in the left-right direction relative to the center on the Galois field and the syndrome calculation in parallel. The syndrome calculator to perform the syndrome calculation method is forward buffer for buffering data to receive the forward, reverse buffer for buffering the received forward syndrome calculator, a reverse data to calculate a syndrome by receiving the forward data buffered by the buffer forward The backward syndrome calculating the syndrome to receive reverse data buffered by the buffer converter, and characterized in that it comprises a syndrome adder adds the calculated syndrome calculated by the syndrome and the syndrome calculator reverse by the forward syndrome calculator shall be.
