Today's conventional techniques do not address reducing specific power elements such as glitch power in deep logic levels and dynamic power in high-performance datapath pipelines. The DesignWare minPower Components offer unique, power-optimized datapath architectures that enable DC Ultra™ to automatically generate circuits that suppress switching activity and glitches, reducing both dynamic and leakage power for mobile devices and high-performance applications. Based on the actual switching activities, transition probabilities, available standard cells and analysis of possible configurations, the DesignWare minPower Components architectures are automatically configured by DC Ultra to implement the optimal structure with the lowest power consumption. In addition to the automatically inferable components, the DesignWare minPower Components also include more than 40 instantiable blocks that incorporate low power design techniques such as enhanced clock gating, built-in datapath gating and patented data-tracking pipeline management technology to reduce power consumption.

By using the DesignWare minPower Components, leading wireless, networking and DSP companies achieved power reduction of up to 48 percent in datapath logic. The table below shows the overall improvements in area and power in datapath circuits as recorded from initial customers designing wireless connectivity and high-performance networking applications. While the total chip power reduction achieved with the DesignWare minPower Components will vary, initial customers have reported design power reductions ranging from 2 to 20 percent in tested modes.

DesignWare minPower Components
