how do they - Gary streams from andrew authority we're here at Mobile World Congress I've stopped by the Sivir stand who make DSP technology now have met up here with Aaron he'll tell me a bit about them and what they do hi oh nice to meet you hey Larry so well yes eBay is basically a DSP provider we provide IP just similar business model to arms only for DSP so we have four product lines basically one for image processing and published recognition in your network stuff like that one for audio and voice and sensing technologies another one for cellular technologies and another one for connectivity that Bluetooth and Wi-Fi so it all comes in the form of IP where you can integrate that interior of SOC and here we have their solution which is actually integrated into the galaxy s7 doing the speech recognition so whenever you say ok Google to your Galaxy s7 that's our technology inside through one of our silicon partners DSP group they make the chip and the interesting thing about the galaxy s7 is that Samsung chose to use the Snapdragon 820 as the application processor now the a20 has its own ultra-low power island for these type of occasions the speech recognition etc for always-on applications and despite that Samsung still chose to use the DSP group solution with our deep inside specifically because of its internal power consumption even compared to that low power and of the Snapdragon so once you look at the total PCB you can see here and that over there in blue is the DSP group chip during the speech recognition so from my perspective that's a very important design win indicating of the internal power consumption of our solution that's really amazing I didn't know that that was there inside the s7 so that's that's amazing and I see here also we have a smart speaker which is the kind of things that are coming to our home nowadays we've got products from Google and from Amazon you're also in this field what do you do here yeah so basically it's it's a similar concept of speech recognition only that in the smart home space and smart speakers you want to have the far field capability unlike smart phones or smartphones are usually near field although we start hearing about a trend of integrating far field capabilities even into smartphones now why is that because you have four mics or three or four mics in most smart phones today so you could theoretically do the far field capabilities the thing is power consumption again the smartphone battery is much smaller compared to this smart speaker battery so power consumption is crucial again but still again with the our silicon part of this B group you have multiple design ways already for smart speakers and the difference here so in the galaxy s7 for example this is a single microphone solution in a smart speaker as you can see here in this demonstration Dell three microphones and the number ranges between two mics like in the Google home to seven mic luck in the Amazon echo or eight mics like in the dingdong but basically this it's a multi mic application and again power consumption is crucial so that's a similar concept only applied to a multi microphone setup and it it also involves additional technologies at beamforming acoustic echo cancellation the reverberation so other technologies needed forward the far field pickup to handle all those echoes and also this device emits music so you have to consume the music that's why we have the acoustic echo console and in a DSP is brilliant for all those different things you just mentioned exactly that involves intensive signal processing so and an MCU or CPU is a no-go for that type of application it's not just like a sensor you know like 100 Hertz sensor those sensors those acoustic sensors they either 16 2 all the way to 48 kilohertz so and there's there are multiple microphones in such a setup so we're talking about multiple sensors and the horsepower which is required for processing that increases dramatically and yet staying low power which is a secret yeah battery life is key yeah so now we've come over to the Bluetooth Low Energy part of your stand he's got an audio over ble solution and of course Bailey v has just come out and this is more low power and of course we're gonna see this in our smart phones hopefully maybe next year our accessories are gonna get this thing so it's a whole new thing and you're in that space right so we have where the leading provider of IP for Bluetooth and Wi-Fi so we have a Bluetooth 5 solution and one of the main innovations in Bluetooth 5 is as you mentioned the audio over Bluetooth Low Energy so until now we have audio over Bluetooth but that was very per consuming and now we want to have much more much better power consumption so we have Bluetooth audio over ble boost or energy and consider for example in this applications the hearing aids or in general the hero bus or the headset market the wireless headsets so the power consumption is critical because the batteries are very tiny especially in the so you don't want to mess with the batteries every few hours like you do with your Bluetooth headset so perception is critical and indeed the audio rebuilding enables you to enjoy audio over Bluetooth but with much lower power consumption that you could before Bluetooth 5 well this is amazing so you are like the hidden heroes of the of the voice of audio because your stuff is built into other people's chips and that's we as the consumers at the end benefit from that and I think that's absolutely great thank you very much for your time today thank you
