SOMNIUM® DRT is a complete C/C++ embedded software Microchip SAM examples Atmel START was used to create an "empty" C program including Atmel Software Framework development environment which supports ARM® Cortex® M (ASF) routines to configure the on-chip PLL to highest devices from leading semiconductor vendors. possible frequency on a SAMD21 device (32KByte ROM, Vendor Family Cortex 4KByte RAM).

NXP Kinetis examples We used NXP's Kinetis SDK v2 (now No defeat devices! Unlike many well known software renamed as MCUXpresso SDK) tools to create an "empty" C vendors, SOMNIUM play fair and do not put “benchmark program (including use of Kinetis SDK v2 routines to enable special” features in our products to change their behavior in the on-chip PLL) for a KL25Z device. DRT saves a significant the presence of known tests. We don't alter the benchmark amount of ROM compared to both vanilla GNU tools and source code, and we always use the same tool options to get IAR tools. an honest and fair comparison.

K21 devices K21 use an M4 processor and has an extreme performance memory system with a 128-bit speculation buffer and a 16-entry, 4-way 128-bit line set associated flash cache. Even with the K21's sophisticated cache, DRT provides significant energy savings, whilst also reducing codesize and improving performance.

NXP Kinetis results We compared against the latest KDS3.2 tools (which use an older version of the GNU ARM Launchpad tools to avoid some code generation bugs present in newer versions of the NXP LPC results vanilla GNU tools), and also compared against the latest We compared DRT to the LPCXpresso/MCUXpresso tools vanilla GNU ARM Launchpad tools used in the MCUXpresso which use vanilla GCC5x (similar to the GNU tools as used in IDE.
