2. 2 The Internet of Things Today Enormous potential  “Tens of billions of new devices”  … but market growing slower than expected Embedded, but different  IoT devices are often “embedded” but can have different requirements, constraints and goals compared to conventional embedded systems  Often very strict energy or resource constraints Complexity rapidly increasing  Security, manageability, updates often underestimated  More sophisticated hardware requires more software … and vice versa!

3. 3  Embedded development is a specialized skill  The tens of millions of non-embedded developers struggle with the low-level environment, lack of libraries and strict resource constraints  Conversely, embedded developers struggle with internet protocols, servers, security, networking, etc  Even with good embedded developers, embedded software is expensive, slow to market, and getting worse!  Power management is important, but difficult  Allowing the programmer to manually manage power requires they deeply understand the hardware  Hardware often consumes energy in non-obvious ways  Most software is not re-used  Less than 25% of embedded projects use third-party software components [Source: UBM Embedded Market Study 2013]  Software re-use lowers costs, time-to-market, and fosters protocol interoperability and security  Connectivity introduces many new security concerns  Previously isolated devices now at risk of remote attack, data leaks, and denial of service  Security is also a specialized skill; non-experts often introduce subtle vulnerabilities Challenges

9. 9 ARM mbed OS Philosophy Reducing total system cost by enabling better system tradeoffs We care about this. … if it results in savings here … (e.g. sophisticated power management) But it can make sense to spend more here … (e.g. on more memory) = + + Total CostHardware CostEnergy CostDevel. Cost (amortized, inc. deployment cost) … and here. (e.g. firmware update, manageability)

10. 10  Use higher-level languages that allow the developer to express their intention more succinctly and concisely, with less chance of mistakes  mbed utilizes C++ for ease of development  Better tools  Automated testing infrastructure  Improved debug and diagnostics support  Increase software reuse  Online community for sharing components  Automate the process of incorporating software components into a project  Commonly used functionality bundled into the OS  Consistent power management ARM mbed OS Philosophy Increase developer productivity and reduce development costs
