Abstract: A light emitting device driver circuit includes: a power conversion circuit, an error amplifier circuit, a sample-and-hold circuit, a load current generation circuit and a feed-forward capacitor. When the light emitting device driver circuit is in a disable phase, the sample-and-hold circuit connects a feedback signal with a second reference voltage and the sample-and-hold circuit disconnects the feedback signal from a load node, whereby the feed-forward capacitor samples a sample voltage and holds it after the disable phase transits to an enable phase. In the enable phase, the sample-and-hold circuit disconnects the feedback signal from the second reference voltage and the sample-and-hold circuit connects the feedback signal with the load node, so that during a predetermined period following the transition, there is a sufficient difference between two input terminals of the error amplifier circuit so that the load current is raised to a desired current level within the predetermined period.

Assigning each of the non-speculative processing tasks to a respective processor of a processing system specific to each design partition for timing analysis processing is done prior to assigning any of the speculative processing tasks.
