 So we had the Lunar Connect with the same chips and who are you? I am Xinzhou from Sendchips So Sendchips is a chipset company of ZTE, right? Yeah, it's a sub company of ZTE And you have some some NB IoT and some TV box solutions right here. So what are you talking about right here? This is our NB IoT chipset and The official name is the Rosefinch 7100 So this is a Rosefinch 7100 NB IoT with a Cortex M0 MCU and what is this is running Zephyr? Zephyr is the operating system. We apply this operating system in our solution Open source RTAS? Yeah, yeah Is everything very stable? Everything is working? Everything is working fine, but the networking Maybe need a more improvement That's important for NB IoT to do good networking, right? Yeah, it's correct. So what is the improvement that's needed? Stable and then eventually and the speed Something like this. What is this board? Is it the development board or what is this? Yes, it's EVB board and there's all four features and in the future we'll make the size smaller and smaller So all these connectors for something? It's for your tech or some external pin export And maybe you can make a board very small, no? Yeah, it's very small. How soon? It's like a module. Just like a small size about maybe Maybe very small about this small corner the corner of this. Yeah, this is this is our debug tool This is a SDE send chips development environment So it works with your chips or specifically with that one? This is for debugging. You can see this picture. Yeah, yeah, because the core Core module is open OCD. It is open source provided by Leonardo We apply the solution in our SDE solution. What is open OCD? Open OCD is It's a connector GDB and adapter So it's an open solution for connecting For connecting the systems together. Yeah, that's right And there is a very important to the core module of this solution And what are you showing up on here? This is This is our SDE feature list and the next one is multi-media chip. You can see on the left That's the one right here. Yeah, it's right right now. It's doing Chromecast. What is it down the entry? It's for DRM solution and we can play with the de-crafted image de-crafted image It's for China DM and And And the one-on-one this is the DRM solution. So you you implement a trusted execution environment. Yeah OPT OPT OPEN you do the OPT OPEN OPEN T security solution It's working. We're working fine. And this chipset is very popular, right? Is is it where this one there? This one there. It's a RM Cortex a53, right? quad core a53 So it can run for example Android TV and your TV. Yeah, that's the most popular one. Yeah, only mostly Android TV. Yeah, and then Together with the narrow you optimize and you make OPT work, right? Yeah, and for some secret port, a secret storage and a secret playback and the secure update and STP some security feature Will you guys mentally? Yeah, so there's a IoT segment TV segment Sane chips make many different CPU many different. Yeah, maybe for example smartphones No, no smart phones IPTV IPTV. So IPTV and IOT Market, right? Yeah, that's right. And everything is better to do in open source. Yeah, you think yeah, I think yeah so so does mean the it's an important strategy for Sane chips to work together with the Ecosystem to make standards, right? Yeah, it makes sense and when connect cooperation with a narrow and we do some upstream work in open source Can only how do you work with the narrow? About more than two years Yeah, same chips started two years ago for you. Oh, I Work with a narrow more than two years and the same chips enter narrow or some organization about About three or four years. So It's supposed to work every day the whole year to do Over the internet working with the community Yeah, yeah How's the linear? How's this week busy week? It's very busy. Yeah, what do you have meetings or? some sessions and the meetings and discussing with SWT KWT light and some The narrow guides. Yeah, what is your role? What do you do? Are you in charge of operating system and the security architecture and So see somewhere vacation something like this. So about the security Yeah, Cortex M zero is arm V seven with seven right. Yeah So the V8 M will have hardware security. Maybe it's important also, right? Yeah, yeah, I know so I entered some I'm tearful for the V8 M and And I discussed with IOT solution solution with our guys and the narrow guys
