Building the Future of AI on Intelligent Accelerators
In this blog, I dive a little deeper into the options to efficiently couple a processor from the X100 series to a hardware accelerator.
Enabling AI Innovation at The Far Edge
Away from the performance headliners and press articles about the cloud industry, there is a vast opportunity for tinyML at the far edge. This is a diverse collection of sensor-rich endpoints that collect, pre-process, and analyze real-world data prior to submitting metadata to the cloud. Learn about how SiFive products are driving innovation across this space.
