The platform is built around a power-optimized CEVA-TeakLite-4 DSP and subsystem implemented SMICs IoT-centric 55nmLP process. Running at 500MHz, the DSP provides designers with a powerful means to add ‘smart and connected’ capabilities to these devices, including always-on sensing, local processing and intelligence and connectivity. The platform also provides real-time power measurement that allows developers to optimize and power-tune their DSP software.
The CEVA Smart and Connected Development Platform incorporates the following elements:

DSP development chip: 500MHz CEVA-TeakLite-4 and subsystem of integrated peripherals

Host CPU: Linux running on-board ARM Cortex-A9 for complete CPU + DSP system prototyping

Connectivity: multiple wireless technologies available from CEVA and its partners, including Bluetooth Smart and Smart Ready, Wi-Fi, ZigBee and GNSS

Peripherals and interfaces: including on-board digital (MEMS) microphones, I2C I/F for sensors, audio CODEC with digital and analog audio in/outs, USB, UART, PCIe, and Ethernet ports, user configurable FPGA, GPIOs, DDR memory, SD card, and LCD display

Arduino connectors and drivers: allows Arduino Shields to be connected to the board, leveraging a massive ecosystem of Arduino-related products

CEVA’s Android Multimedia Framework (AMF) for offloading Android tasks from CPU to DSP to enhance always-on functionality and long audio playback time

RTOS and DSP libraries: multi-tasking RTOS and a DSP library to jumpstart system design

In the CEVA partner ecosystem are also available audio, voice and sensing software and applications that are optimized for the CEVA-TeakLite-4 DSP, including Sensory’s always-on voice activation and speech recognition, NXP Software’s multi-microphone noise reduction, Cypher’s neural-network based voice isolation technology, Cywee Motion sensor-fusion algorithms and more than 100 other software functions.
