Embodiment Construction

[0047] Apparatus and methods for signal flow aware power routing are described. In one embodiment, the programmable routing system is configured to route the power supply signal from the generator circuit to one or more functional blocks based on the signal channels of the functional blocks. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known circuits, structures and techniques have not been shown in detail but are shown in block diagram form in order to avoid unnecessarily obscuring the understanding of this description.

[0048] Reference in the description to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodimen...

Description

[0001] related application [0002] This application claims the benefit of US Provisional Application No. 61 / 621,408, filed April 6, 2012, which application is incorporated by reference in its entirety. technical field [0003] The present disclosure relates generally to microcontrollers, and in particular to microcontrollers that are part of a mixed signal array. Background technique [0004] A microcontroller can have an embedded processor, memory, and special function analog and digital circuits. Typical analog circuits found in prior art microcontrollers include continuous-time (CT) amplifiers with preset functions using given function parameters. For example, a CT analog amplifier may be configured as a fixed-function circuit, such as a voltage amplifier, where certain parameters, such as gain or bandwidth, may be changed by programming. [0005] Switched capacitor (SC) analog circuits are also often incorporated into microcontroller designs. Because it may be possib...
