Zusammenfassung:An error correcting code generator and a wireless transmitting and receiving apparatus comprising the same are provided to generate an error correcting code at a high speed by processing data in parallel. K shift registers are divided into k groups according to classification manners for classifying flip-flops(D1-D16) corresponding to the highest order of an error detection code generation/inspection polynomial. The K shift registers generate k output data by inputting and shifting k input data in response to a clock signal. A plurality of first exclusive OR gates are connected between output terminals of the flip-flops and input terminals of the flip-flops in order to perform exclusive OR operations for the data of the output terminals of the flip-flops corresponding to the order-x of the polynomial and the corresponding output data of the k output data. A plurality of second exclusive OR gates performs exclusive OR operations for the data of the output terminals of the flip-flops corresponding to the highest order-y of the polynomial and the corresponding output data of the k output data.
