 So here you have Zephyr running on the ARM Cortex M33 new class processor, right? That's right. This is a demonstration of trusted firmware for M-class devices. We took on ourselves to integrate Zephyr with trusted firmware. We started this work on Monday when we actually reached here. You started on Monday? Yes. And right here we're looking at a special kind of configuration right here. There is an ARM Cortex M33 in there. So yeah, this is a MPS2 FPGA board where you can program Cortex. This is basically a programming board where you can put all the M-based systems or any Cortex M3. So there's an FPGA? And it has an FPGA. If you look at the board on this side, this is running a caster subsystem. This is a caster subsystem which is essentially based on CM33 with a lot of security IPs integrated with this. And this board is hardware level isolation. So you might have heard about the trust zone on for V8M. This hardware supports all V8M trust zone related IPs. And this demonstration showcases the integration of trusted firmware M project with Zephyr. Where Zephyr is actually running on the non-secure side. The trusted firmware is actually a trusted firmware running on the secure side. If you look at the demo, this is showing interaction between non-secure world and secure world. On the non-secure world, Zephyr is running as the, well, your hard task. It's running the scheduler, it's running some other tickers. And in one of the tasks, it's essentially making calls to the secure world and it's storing certain objects, then reading it back and comparing if it is the same or not. So it's showing the whole path from non-secure world to going to the secure world and coming back. And at the same time making sure that all the parties which is secure as well as non-secure they're happy with the whole setup. So it's essentially showcasing that the non-secure world of RTOS can happily integrate with the DFM without much other problem. The fact that we started only on last Monday is kind of proof that it's a step in the right direction. It all makes sense. It took less than two days to integrate a completely new RTOS which did not have any security or trust zone awareness in the past. And we did not have to make a single line change in the trusted firmware M. I think it's another proof that it's headed in the right direction. So is there a real Cortex M33 or is it emulated on FPGA? This is a well, it is emulated on FPGA but it's actual RTL. It's not a simulation or a simulation. So it's the actual design of the M32? It's actual design of the M33. In just five days you were able to modify Zephyr to support it? I would say less than two days because the actual time spent was much less than four days. We got it running yesterday morning but in between we had a lot of sessions, a lot of other discussions. So the actual effective time spent on doing this demo is probably less than two days. And this is the ultimate secure IoT platform for the future? This is the ARM's reference platform for showcasing how an IoT system should be done with ARM's IPs with hardware security? With hardware security which is ARM plus zone. And as I said in the past it provides hardware level isolation between the secure and non-secure domains. And this demo is essentially showcasing that separation and showing that it's the software that we have designed for secure world is compatible with the already existing non-secure operating systems. So this is going to be 100% secure? What do you think? I think that's the step in the right direction. As I said the trusted firmware project we just made our first release in December last year. So it still has a lot of miles to cover but it's a step in the right direction. And at this point we would like collaboration and basically feedback from all the involved people. All the people who are doing IoT security or security in general. I would like to invite them and start looking at the implementation and start giving us feedback. Start getting involved in the trusted firmware.org project which is now open governance project. And this is the M33 chipset and the M23 are coming very soon. They're like Nordic Semiconductor announced one and the other company also. NXP maybe? I may not be able to comment on the chipsets coming from other partners. But from ARM the Caster and the Muska solutions are the one which is basically codex M33 based. I think there are solutions coming up but I may not be able to talk about the partners specific details.
