Introduced for more than three CRC procedures bitwise slower method, but the memory space occupied by the smallest by byte CRC look-up table method for faster, but occupy a larger memory by a half-byte look-up table CRC seek ways to balance the first two projects, namely, not taking up too much memory, at the same time does not slow the pace more suitable for 8-bit single-chip small-memory applications. The above procedure can be given by C compiler based on the characteristics of the microprocessor to make the corresponding changes, such as the CRC-style table than on the storage area, such as procedures.
