Abstract
An error detection circuit and method for performing cyclic redundancy check on a clock gated register signal is disclosed. The error detection circuit comprise a first register, a second register, a third register and an error detection module. The first register is a clock gated register and is configured to be updated with a data signal (x) in response to a clock enabling signal. The second register is configured to be updated with a check bit (c) based on the data signal (x). The check bit is calculated by a check bit calculation unit. The third register is configured to be updated with a current value (b) of the clock enabling signal. The error detection module is configured for calculating an indication bit (I) based on at least the output of the first register, the output of the second register and the output of the third register.
