CMSIS Roadmap Continues To Evolve….

New proposals being discussed with partners

CMSIS-PACK: Accelerate software development

Software packages in ZIP format

XML based description files

Easier middleware integration

Better software reuse

Include toolchain and compatibility information

Demonstrated with Keil MDK 5 beta

(http://www2.keil.com/mdk5/)

CMSIS-Driver: Unified device driver API

Consistent driver collection for middleware

Potentially on-top of silicon vendor’s drivers

Still allow for differentiation

Energy Efficiency is The Next King

Many new ARM based microcontrollers are under 100uA/MHz

New benchmarks being developed:

EEMBC and VOLKSWAGEN to Develop Benchmarking Standards

to Quantify Microcontroller Energy Efficiency (May 2013)

Performance (system level - including peripherals)

Power / energy efficiency

Latency

EEMBC aims to create ultra low power microcontroller benchmark

(Jan 13)

Processing efficiency

Low power on-chip memories is the next frontier

e.g. Flash sampling technique in ATMEL SAM4L

(www.atmel.com/images/Redefining_the_Power_Benchmark.pdf)

MRAM / FRAM technologies entering MCU designs

23

Internet of Things (IoT)

Many pieces of the puzzle are ready / almost ready …

Ultra low power microcontrollers - for always on systems

Weightless SIG – v1.0 of the specification has arrived (April 2013)

Low power wireless communication standard targets at M2M

Low cost

>10Km range

Software ecosystem building up…. e.g.

Oracle Java ME 8 – expect Q1 2014

Smaller memory footprint

Peripheral APIs

Increasing demand for middleware

Protocol stack, GUI library, file system, crypto, multimedia…

Still lots of issues to solve

E.g. Application level M2M protocols

http://www.weightless.org

24

Where are the Opportunities?

Sensors

Energy management, security, monitoring

Motors

Preventative maintenance, performance monitoring

Medical monitoring

Chronic disease management, on-body wellness tracking

Asset/Goods Tracking

Hospital equipment, RFID “from a distance”

The Previously Unconnected

Streetlights, traffic signs/lights, parking meters, vending machines

Middleware

Communication protocols, crypto, GUI, multimedia processing

IoT Platforms
