IP plus software builds low-data-rate over-the-air interface for M2M

February 09, 2016 // By Graham Prophet
A communication reference platform for machine-to-machine (M2M) SoC designs, IP vendor CEVA’s Dragonfly reference platform aims to reduce time-to-market for power and cost-sensitive IoT and M2M devices supporting low-data rate connectivity, including LTE Cat-1, Cat-0, Cat-M and NB-IoT standards.

Dragonfly targets (M2M) and IoT communication applications, including standalone wearables, smart grid, surveillance systems, asset tracking, remote monitoring systems, connected cars and smart utilities. It is based around the CEVA-XC5 and CEVA-XC8 DSP cores and accompanied by the hardware and software components required to rapidly design machine-type communications (MTC) systems. The platform supports existing and emerging LTE MTC releases, LPWAN standards (e.g. LoRa, SiGFox, Ingenu), in addition to Wi-Fi, GPS or any other IoT-related communications standard set to be deployed for M2M communication.

Dragonfly offers system developers – CEVA says – a flexible platform that allows for optimal hardware/software system partitioning, combining a low power vector communication DSP with a range of hardware co-processors. Such partitioning enables software flexibility for upgradability and long service life of typical M2M devices, while delivering the power efficiency required to support extended battery life of up to ten years.

The Dragonfly reference platform includes the vector communications DSP and all the required co-processors and interfaces, together with software application layers and libraries, RTOS and drivers for MTC systems design. These hardware and software components are available for LTE MTC, Wi-Fi and GNSS standards. Also included is a 500 MHz silicon-based development system that includes all of these components together with RF frontends and a host interface.
