Problems faced by embedded developers

Time to market is important
 Only 38% of projects are on time
 62% of projects are late!
 Every year its getting worse ...

Choose your microcontroller wisely
 Many chips are similar
 Ecosystem is important
 Not all ecosystems are equal ;-)

SOMNIUM® DRT is the solution

SOMNIUM® DRT -
Professional C/C++ development environment
Save memory
smaller ROM/RAM device, lower cost designs
Save money
faster time to market, optimize BOM costs
Increase performance
more features, “do more with less”
Save energy
higher quality design, reduce lifetime costs

DRT recognizes that memory is the bottleneck
SOMNIUM® DRT optimizes for the whole system
It dominates
performance and cost

Measuring energy consumption
 SOMNIUM are members of the EEMBC®
Automotive Subcommittee and use their
industry standard benchmarks.
 We measure energy, measured to the uJ using
the high accuracy EEMBC EnergyMonitor™
 EEMBC CoreMark™ is used to demonstrate the
usable performance of a processor system
running typical algorithms including list
processing (to stress test data accesses), matrix
manipulation (to stress test and mathematical
operations, and state machines (to stress test
complex control flows).

Wide range of performance and energy options
Higher performance
Lower energy
More expensive
Extreme performance

DRT is benchmark proven:
Smaller, faster, lower energy
EEMBC® CoreMark® built with DRT
Up to 54% higher performance
Up to 44% lower energy
Up to 14% smaller ROM
Up to 21% smaller RAM
