Example Embodiment
[0023] The present invention will be further described in detail below in conjunction with specific embodiments, which are to explain rather than limit the present invention.
[0024] The present invention provides a glitch-free switching circuit that supports multiple clocks. First, denoise the clock switching request, and then save the clock selection signal based on the valid clock switching request, and then perform a unique operation on the saved clock selection signal. For hot code decoding, only 1 bit of the decoding result is high, and then the multi-clock interlock circuit will process the decoding result according to the current output clock enable (marking the current output clock). If the current output is If the clock enable is zero, the decoding result is directly passed to the input of the clock management circuit; if the current output clock enable is non-zero, the decoding result is compared with the current output clock enable. If the two are inconsistent, The i...
