RAPTOR - TinyML & Edge AI Platform

Speed up your algorithms at a fraction of the energy spent by your CPU

Technology for better future

The solution to deal with data deluge, while preventing the increase of power consumed by data centers, is known as Edge AI. This solution consists in transferring most of the processing intelligence from the cloud to the sensor. It translates into an unprecedented need to increase performances of «smart devices» by a factor of 1,000 at constant energy consumption.

With our SPEED IP platform, we are positioned as THE provider of solutions for Edge AI System-on-Chip designers. We enable our customers to do much more with less energy resulting in major benefits on environment.

RAPTOR Neural Processing IP Platform

Tiny RAPTOR is a Power efficient Neural Processing IP Platform specialized in sound and vision. Tiny RAPTOR’s near-memory computing architecture is composed of a DMA, local memory and up to 128 processing elements in its most powerful version.

Tiny RAPTOR is a fully programmable accelerator designed to execute deep neural networks (DNN) in an energy-efficient way. It reduces the inference time needed to run Machine Learning (ML) Neural Networks (NN). Tiny RAPTOR fits particularly well within any MCU subsystem, in particular with our MCU subsystem CHAMELEON.

In order to implement efficient data processing solutions at the edge, MCU architectures need to be modified.
Firstly, an efficient fine-grained data power network needs to be implemented, optimizing not only leakage, but also dynamic power.
Then a new sensor-centric approach must be implemented, to avoid involving the CPU in all events in the case of large data collection.
