Hello, Can I ask how can I design a circuit about Cyclic Redundancy Counter Generator without using microcontroller. We need to apply the crc generator in real life. Thanks

 

If you don't need a discreet logic design something like this might work.

If you do need a discreet logic design for something simple, this should help.

What does needing it in real life have to do with anything? A need for a practical application screams out even more to just use a simple, cheap microcontroller.

Which CRC are you trying to implement?

How is your data being received? Parallel? Serial? If parallel, is it msb first or lsb first?

What is your CRC going to do with the value it generates? Indicate if the embedded CRC value doesn't match? Add the CRC to the data stream?

A LOT more information about your application is needed.

 

You can build a CRC Generator/Checker with a shift register and exclusive OR gates.
The single chip implementation would require an FPGA. Doing it with MSI (Medium Scale Integration) chips would be impractical in terms of number of chips and board area.
