Abstract
The present invention has been made in view of the above mentioned problem, and the present invention provides a sticky signal generator for rapidly generating a sticky signal with a small layout area which uses a shift register of which the size is equal to the size of the inputted operand data. In accordance with the present invention, there is disclosed a sticky signal generator including: a plurality of shifters for shifting an input data by a shifting width in response to at least one of shifting width control signal, wherein the size of the shifters is equal to the size of the input data, and the plurality of shifters are coupled serially to each other; a plurality of selectors for selecting and outputting the bits which are discarded by the shifters during shifting operation in response to the at least one of shifting width control signal, wherein each input terminal of the plurality of selectors are coupled to each of corresponding shifters; and a detector for determining if a bit of predetermined logic level is included in at least one of outputs from the plurality of selectors, and outputting a sticky signal in case the bit of predetermined logic level is included in at least one of the outputs.
