CHAMELEON MCU Subsystem

- Flexible & pre-verified event-based IP architecture
- Fast & efficient CPU-less data collection & filtering
- Fully interoperable with SPIDER power management platform

Moving data and decision to the cloud led the whole industry to a new power and time-consuming challenge: the data deluge.

The best way to limit it is to reduce exchanges with the cloud by priorising local decisions at the edge level.

Benefits are multiples:

  • Faster response time
  • No need for constant connectivity
  • Higher data privacy
  • Longer battery lifetime

The stake is to select cost-effective solutions enabling to reduce drastically the power consumption of such local decisions.

HERE COMES CHAMELEON MCU SUB-SYSTEM

Event-Based MCU Sub-system

CHAMELEON is a flexible & pre-verified  event-based MCU subsystem platform embedding several standard peripherals, an autonomous DMA, a fined-grained power management unit, a tiny ML accelerator, a low latency interconnect, and an event manager.

It allows fast and efficient CPU-less data collection & filtering, enabling extremely low power consumption in both deep sleep and active modes.

CHAMELEON is preinstanciated for Cortex M and can be configured for other cores. 

It is fully interoperable with our SPIDER power management platform.

The platform comes with an RTL configurator tool and all necessary drivers.

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.
