CE40 UltraPlus reference designs support machine learning

Lattice Semiconductor has released reference designs for the iCE40 UltraPlus power-efficient, parallel processing for sensor stitching and repetitive number crunching. It delivers new machine learning and sensor-to-cloud security, says the company, for intelligence at the edge.

The reference designs offer resources to develop differentiated products for smartphones, wearables, drones, 360 degree cameras, human-machine interfaces (HMIs), industrial automation and internet of things (IoT) security

The reference designs are based on Lattice Semiconductor’s iCE40 UltraPlus field programmable gate arrays (FPGAs). They support LoRa communication, elliptic curve cryptography (ECC) security, signal aggregation, machine learning and graphics acceleration.

Lattice Semiconductor’s iCE40 UltraPlus is energy-efficient for sensor stitching and repetitive number crunching, making it suitable for offloading power hungry application processors in battery-powered devices. Lattice claims that its small form factor, low cost and low power FPGAs offer enhanced memory and more digital signal processors (DSPs) to improve system performance and extend battery life.

Built upon existing IP and paired with the new reference designs, the iCE40

UltraPlus enables sensor-to-cloud security and acceleration at the edge, performing data capture, aggregation, encryption, processing and transmission.

For machine learning, or on-device artificial intelligence (AI), the iCE40 UltraPlus FPGA reference designs employ trained neural network algorithms for always-on, low power human face detection using a low resolution image sensor.

For graphics acceleration, the reference design supports always-on graphics such as clocks in mobile and wearable device displays with low power consumption, while the application processor is dormant.

It encrypts sensor data before transmission to the cloud or can set up an authenticated communications protocol between two systems for ECC security.

It can control a LoRa-compatible radio to send processed sensor data across distances measured in miles.

The iCE40 UltraPlus is the latest addition to the iCE40 Ultra family, delivering eight times more memory (1.1Mbit random access memory – or RAM), twice the DSPs (eight) and improved I/Os, compared with previous generations.
