Abstract

An integrated circuit device may include processing circuits that can be dynamically reconfigured to perform different tasks each of which utilizes different system clock resources. The device may include clock selection circuitry that can selectively route desired clock signals to corresponding processing circuits. The clock signal provided to each processing circuit may be selected based on a current configuration of that processing circuit. Client processing circuits in a network switch may be coupled to interchangeable client networks. The client processing circuits may be dynamically reconfigured based on characteristics of the client networks that are currently coupled to the network switch. By dynamically selecting which clock resources are provided to the processing circuits, clock resources such as global clock signals that are relatively scarce may be reserved for processing circuits that can only function with the relatively scarce clock resources. Arranged in this way, clock resource utilization may be continuously optimized.
