A WORLD OF OPPORTUNITY, BUT
« There will be trillions of these IoT devices out there »
Jensen Huang, CEO of NVidia
« The speech and voice recognition market is expected to be valued at USD 6.19 Billion in 2017 and is likely to reach USD 18.30 Billion by 2023, at a CAGR of 19.80% between 2017 and 2023.»
Markets and Trends
« One of today’s technology most significant challenges is how to create a SOC that meets the conflicting consumer demand for devices with both high performance and extended battery life »
Samsung Semiconductor business
« …Power management is another feature, which in some cases may be the determining factor for whether a product (MCU) does well or fails because it affects battery life. Some of these MCUs have more than 16 low-power states, but to transition from one power state to the next is complex. »
Andrew Caples, Mentor a Siemens business
« The IoT technology market is expected to grow from USD 176.00 Billion in 2016 to USD 639.74 Billion by
2022, at a CAGR of 25.1% during the forecast period. »
