Developing and verifying a control network in a low-power SoC is a challenging task, especially managing the different states of regulators and modes of power domains.
This article first describes state-of-the-art approaches to addressing this issue, and then delves into the solution promoted by Dolphin Integration to go further, thanks to the easy and secure Maestro� solution to manage SoC power mode transitions.
Allowing battery-powered devices to run, without battery recharge, for years rather than months, partakes in enhancing significantly end-user satisfaction and is a key point to enabling the emergence of IoT applications. Numerous applications, such as M2M, BLE, Zigbee…, have an activity rate (duty cycle) such that the power consumption in sleep mode dominates the overall current drawn by the SoC (System on Chip). For such applications, the design of the “Always-On power domain" (a.k.a AON power domain) is pivotal.
In this fifth and last part of Paving the way for the next generation audio codec for True Wireless Stereo (TWS) applications whitepaper, a hastened but safe and improved design flow by Dolphin Design will be discussed.
The Internet of Things (IoT) is the latest buzzword driving the industry for any number of low-power interconnected things. However, the IoT encompasses an incredible number of different types of things ranging from edge objects, namely smart or wearable devices which are battery powered with sensors and wireless connectivity, through aggregation nodes, namely hubs, routers and gateways for data aggregation, up to information processing servers in the Cloud to handle the data pushed by edge objects.
Today’s energy metering standards demand higher accuracy and lower power consumption which, in turn, challenges system designers to deliver more competitive AFEs. This article reviews those challenges and presents a solution based on a multiplexed channel architecture that delivers ultra-high resolution, along with very low-power consumption and silicon area.
The free lunch offered for decades by Moore’s law is now over and scaling down to the next technology node no longer offers the required energy efficiency gains. Design teams must now pursue their gains by deploying increasingly complex power management techniques to meet the demands of the new IoT markets.
