The scope shows overall step counter, the two shift level contents and the trigger signal. WebThis CRC is typically implemented in hardware as a lin-ear feedback shift register (LFSR) with a serial data input (see Figure 1 ). In many cases the serial LFSR implementation of the CRC is suboptimal for a given design. Because of the serial data input, it only allows the CRC calculation of one data bit every clock.
