WebMay 29, 2024 · 1 Answer Sorted by: 1 There are a few ways to do this. In essence, what you need to do is 'unroll' the shifting part of computing the CRC so that it gets evaluated combinatorially within one clock cycle. One way to do this is with a for loop inside of a combinatorial block. WebJan 2, 2008 · In hardware, CRC calculation is done using the Linear Feedback Shift Register (LFSR). The LFSR constitutes D-flip-flops and XOR gates. As shown in Figure 2, the number of shift registers is equal to the degree of the selected generator polynomial.
