Abstract

A syndrome calculating circuit in a BCH decoder capable of correcting one or two errors and detecting three errors is disclosed. In the circuit, an exclusive OR gate(1) exclusively ORs input data and an output of a flip-flop(11). A flip-flop(5) stores an output of exclusive OR gate(1). An exclusive OR gate(2) exclusively ORs outputs of a flip-flop(5) and a flip-flop(11). A flip-flop(6) stores an output of exclusive OR gate(2). An exclusive OR gate(3) exclusively ORs outputs of a flip-flop(6) and a flip-flop(11). A flip-flop(7) stores an output of exclusive OR gate(3). An exclusive OR gate(4) exclusively ORs outputs of a flip-flop(7) and a flip-flop(11). A flip-flop(8-11) sequentially stores outputs of exclusive OR gate(4).
