Presentation Summary

  • Energy harvesting systems further challenge microcontrollers and offer opportunities for extended smart self-operating hardware functions. Energy efficiency benefits from inactive CPU, no code memory accesses and low bus activities.
  • Energy efficiency is optimized on how the hardware is used by which software code sequences. Once this is optimized the encapsulation of this HW and SW enables rapid application development but retain the energy savings. The result of the previous energy optimization effort is still valid independent of later product modifications.
  • Another requirement of energy harvester systems is the ability of the microcontroller to deal with changing energy conditions. The question is how can a microcontroller design ensure robust operation and support self-recovering?

Speaker Biography (Horst Diewald)

Horst Diewald is the world-wide Chief Architect of the MSP430 core, with responsibilities in system and product definition. In his WW role, Horst's main focus is on the future evolution of the MSP430 architecture, the "ultra-low-power" and analog features.
 
During his career at TI, Horst developed the architecture of the MSP430 with a team of engineers. He defined the CPU core, wake-up and interrupt scheme, bus architecture and peripheral system to optimize ease-of-use, high performance at lowest current consumption, and system cost of the MSP430. He holds the basic patent of the low-power scheme, and is co-inventor of the basic patent of the low-power and fast clock scheme which enables "burst-mode" concepts. He also holds a patent for the integrated FLL oscillator concept, among others.
 
He was elected Member Group Technical Staff in 1991, Senior Member of the Technical Staff in 2000, and Distinguished Member of the Technical Staff in 2003
 
Horst is affectionately known within TI as 'The Godfather of MSP430".
