The RAMP chip’s analog blocks can be reprogrammed with application-specific algorithms for detection of both different events and different types of sensor input. For example, designers can use a RAMP chip for always-listening applications in which the chip conserves system power by keeping the rest of the always-listening system in a low power sleep state until a specific sound, such as voice or an alarm, has been detected. Unlike other sensor edge solutions for voice activity detection, the RAMP chip also supports voice-first devices by storing the preroll data required by wake word engines. For industrial applications, designers can use a RAMP chip to sample and select only the most important data points from thousands of points of sensor data: compressing vibration data into a reduced number of frequency/energy pairs and dramatically decreasing the amount of data collected and transmitted for analysis.
With so many ways to program a RAMP core, as well as broad algorithm support for different types of analysis and output, the RAMP chip uniquely enables a whole new generation of smaller, lower-cost, more power- and data-efficient, battery-operated, always-on devices for consumer, IoT, industrial and biomedical applications.
