  • Publication number: 20120173888
    Abstract: A system and method for optimizing power distribution in a closed system. In an electronic device, one may apply a plurality of driving algorithms for components that provide different variations functionality. Thus, each component may be operated according to one of several different algorithms depending on the level and manner of functionality needed. In this manner, the overall system may be optimized for any number of operating modes such that each component may conserve electrical power usage while still providing the needed functionality for specific components during each operating mode. Such an optimization assessment may be a function of an economic model applied to the system whereby functionality and components are assigned specific values and costs based on the required functionality for any given task. Thus, the amount of power available may be allocated in an efficient manner based on a cost-benefit analysis.

  • Publication number: 20120169375
    Abstract: Disclosed is a programmable pulse width discriminator circuit operable to receive a set of parameters from a user and indicate when an input signal satisfies conditions set by the user-defined parameters. The input signal is sampled by the pulse width discriminator circuit to detect a desired state of the input signal. The user may set the parameters such that the pulse width discriminator indicates the condition wherein the number of consecutive samples for which the input signal is the desired state is (i) greater than a first threshold value, (ii) less than a second threshold value, or (iii) between the first and second threshold values. In these embodiments, the user sets the first and second threshold values and selects which set of conditions are indicated by the output of the circuit.

  • Publication number: 20120169376
    Abstract: Disclosed is a deglitcher circuit having a programmable hysteresis. The deglitcher samples a received input signal, wherein the input signal may include one or more glitches. Responsive to a change in state of the sampled input signal, the deglitcher counts the number of samples of the changed state of the input signal. The count value increments with each sampled changed state, and decrements with each sampled original state of the input signal. When the count value reaches a threshold, the state of the output signal is changed. The output signal of the disclosed deglitcher circuit provides an accurate, glitch-free reconstruction of the sampled input signal. Additionally, the disclosed deglitcher circuit reduces the number of memory elements required for a given number of samples of the input signal, thereby allowing for a larger number of samples to be taken without necessarily having to increase the memory elements required by the deglitcher.

  • Publication number: 20120170475
    Abstract: A system and method for optimal allocation of bandwidth in a multichannel transmission channel. In an embodiment, a system may allocate a specific amount of bandwidth in the transmission channel in order to maximize the value of the data that is transmitted on a per-channel basis. Typically, a transmission channel has enough bandwidth to accommodate the minimum bandwidth for all data across all channels. The excess bandwidth may be allocated in an optimal manner so as to provide additional bandwidth for the most valuable channels. The maximum allocation of bandwidth is a point in which allocating additional bandwidth to a channel does not yield any additional value. Such an allocation may be accomplished using an iterative analysis of the available bandwidth and a microeconomic-based analysis of the subjective value of each channel.
