Energy-efficient Edge AI Co-Processor

Supported Frameworks & Applications

Deep learning accelerator ASIC for fast, efficient AI inference co-processing in boards and systems

EdgeCortix SAKURA-I is a single-chip 40 TOPS implementation of EdgeCortix Dynamic Neural Accelerator IP. Its edge AI co-processor core is run-time reconfigurable using the EdgeCortix MERA compiler and software framework. This enables multiple deep neural network models running concurrently while maintaining critical performance characteristics.

EdgeCortix is in a truly unique market position. Beyond simply taking advantage of the massive need and growth opportunity in leveraging AI across many business key sectors, it’s the business strategy with respect to how they develop their solutions for their go-to-market that will be the great differentiator. In my experience, most technology companies focus very myopically, on delivering great code or perhaps semiconductor design. EdgeCortix’s secret sauce is in how they’ve co-developed their IP, applying equal importance to both the software IP and the chip design, creating a symbiotic software-centric hardware ecosystem, this sets EdgeCortix apart in the marketplace.”
