Sensor hubs have played a central role in the recent development of wearable and IoT devices but are now becoming increasingly relevant for other connected devices that require always-on, low power functionality.
This category of chips is currently evolving from performing only simple, individual tasks (e.g. accelerometer, gyroscope, pressure etc.) to becoming a small compute node for contextual awareness that analyzes and interprets multiple data streams; this requires ultra-efficient data fusion from motion, environmental and many other sensors.
Standing Egg sensor hub for mobile, IoT, wearables and automotive
Standing Egg (based in in Seoul, South Korea) has assembled a team of leading researchers to design a complete and easy to integrate sensor fusion solution. The company, one of very few competitive MEMS sensors producers in Asia, has an engineering team that has worked on microelectromechanical systems for more than a decade.
According to CEO Jongsung Lee, the name of the company signifies “the ability to overcome a seemingly impossible problem. Getting an egg to stand is very hard but we are determined to work very hard until we achieve success.”
The initial research work was started from the MEMS Lab at Seoul National Laboratory and most of the engineers working for Standing Egg are experts with 10 plus years of experience in MEMS sensors, SoC design and system-/application-level software development.
The new sensor hub combines an ultra-low power, high performance MIPS M5100 MCU with a range of sensors and interfaces designed by Standing Egg.
The resulting product offers a complete solution optimized for minimal power consumption and increased battery life – a must-have for next-generation mobile devices. The new sensor hubs are also compatible with the latest Android operating system, implementing the stack defined by the Android sensor framework.
The press release issued earlier today says:
Performance, power and area were key decision criteria [in selecting a CPU for the sensor hub]. According to Standing Egg, our MIPS M5100 MCU surpassed other CPUs on these metrics. Standing Egg also determined that the MIPS M5100 CPU can process sensor signals faster and at lower power – an important design consideration for the company. The security features in the MIPS CPU, including anti-tamper technology, also played a key role in the decision.
A block diagram of the Standing Egg sensor hub can be found below:
The highly-optimized sensor hub can be used in a broad range of connected products, including smartphones and tablets, laptops, IoT devices, healthcare, and wearables.
The first products are expected to arrive in H2 2015, with an FPGA version available in advance.
