There is no question about the potential that wearable technology has to take the semiconductor market into a thriving new era of growth. A lot of the innovative devices in wearables have predominantly been driven by chips based around processor IP technologies from Imagination: most smart glasses today use a PowerVR GPU, while a large number of smartwatches feature MIPS CPUs.

However, many wearables today use suboptimal solutions that compromise user experience and prevent widespread adoption. On the low end, wearables generally use multiple chips to achieve the functionality needed, leading to expensive, compromised solutions. Higher end smartwatches generally use retrofitted smartphone processors, leading to overpowered, overdesigned devices that require frequent recharging. For wearables to really take off with consumers, they need to provide the optimal balance of performance, ultra-low power and long lasting battery life.

Providing an answer to this problem has been the aim of Ineda Systems, a company founded by industry veterans who have recently been backed by a number of venture capital companies, including Samsung Catalyst Fund and Qualcomm Ventures in a high profile round of funding.

Dhanush WPUs: a versatile product line designed for wearables and centered on MIPS

Ineda has recently announced the Dhanush family of Wearable Processor Units (WPUs™), the industry’s first wearable SoC designed to meet the stringent power and performance needs of the wearable and IoT markets. Designed from the ground-up, Ineda’s silicon is optimized for long battery life, along with the scalable performance that is required to run various applications in the wearable and IoT space. Ineda offers a range of low power, high performance SoCs designed to support a wide variety of devices, including fitness bands, smart watches, glasses, sports cameras and others.

The first available WPU is Dhanush Micro; it offers customers developing multi-function smartwatches class-leading performance and minimal power consumption. Dhanush Micro will deliver long lasting battery life and increased functionality such as more accurate location awareness and better sensor integration. This makes Dhanush Micro the ideal solution for device manufacturers looking to accelerate time to market and exceed end-user expectations.

Ineda believes these solutions will bring together what is a very fragmented wearables market and drive it to its true potential; to find out more about the company’s platforms and how you they scale for various applications like voice recognition or 3D rendering, visit this link.

MIPS is the ideal CPU for wearable and IoT devices

MIPS is a highly scalable CPU architecture that spans applications from lightweight 32-bit embedded microcontrollers for industrial, automotive and IoT devices all the way up to high performance, industrial strength 64-bit multi-core processors for networking and communications infrastructure. For each of these applications, the MIPS architecture offers high performance, power efficiency and a highly compact silicon footprint, leading to a lower cost, more efficient design.

MIPS CPUs have proven to be the ideal choice for ultra-low power designs such as wearables. MIPS is a sophisticated yet cleaner, pure RISC architecture which achieves better performance at lower frequencies and in a smaller area compared to competing solutions. For embedded and microcontroller-type applications, MIPS CPUs offer industry-leading performance – up to 2.56x higher in DSP operations versus the competition.

This is because we have kept the core architecture extremely compact with minimal frills but introduced a number of unique features such as improved co-processor support, advanced multithreading and hardware virtualization.

The MIPS instruction set architecture (ISA) offers a range of unique power saving instructions, enabling fine-grain control over all parts of the chip. All MIPS CPUs implement fine-grain clock gating to reduce dynamic power and voltage/frequency scaling to allow on-the-fly clock frequency changes. We are also developing our DOKs (Design Optimization Kits) and working with our EDA tools partners to help our MIPS licensees implement low-power design flows which deliver substantial silicon PPA gains while reducing design cycle times.

Collaborating on the world’s first Wearable Processing Unit

Ineda is an innovative partner and one of the first companies to truly understand market requirements and prepare for widespread adoption of wearables. By choosing off-the-shelf MIPS CPUs from Imagination, Ineda is able to build four high performance, low power designs that will be deployed in a number of embedded, wearables and IoT applications.
