EvoluConinElectronicProducts(1/3)
• CompuCngTrend– Main-Frame->PC->NPC/MP->Cloud(DataCenter)->Fog->Edge(Devices)
• CommunicaCons(Internet)– Analog->Digital(GSM)->3G->4G->5G…– Enhancedatarate(>1Gbps)
• ConsumerProducts– Homeappliances->mobiledevices->Internet-of-Things(IoT)->Internet-of-Everything(IoE)…
– MedicalIoTforprevenConmedicine– IndustrialIoTforIndustry4.0(ProducCvity)– Self-drivingvehicles

EvoluConinElectronicProducts(2/3)
• ElectronicProductsmainlyconsistof3layers:– ApplicaCon– OperaConsystem(OS)– HardwaremodulesorSystem-on-Chip(SoC’s)

FromApplicaConstoChips(1/2)
• ApplicaConstobedefinedclearlysothatend-users(orcustomers)woudliketopayformoreservices,i.e.self-definedsystemspecs.
• EssenCalchipscanenablenewapplicaConsandservices,e.g.A#chipsfromAppleforvariousiXproductlines
• Therestchips/modulescanbepurchasedfromothercompanies.
