NXP’s LPC1700 series Cortex-M3 microcontroller has been benchmarked as the fastest microcontroller based on the ARM processor core.
The Embedded Microprocessor Benchmark Consortium (EEMBC) results show that the LPC1700 executes application code on average 35% faster than the leading Cortex-M3 competitors when running at the same clock speeds.
The microcontroller has been certified by EEMBC at 72,100, and 120MHz.
Important factors in the performance seem to be the core’s memory interfaces which include direct memory access (DMA) and high speed flash.
“These certified EEMBC results highlight the fact that the design of the microcontroller and its memory interfaces is equally as important as the processor core itself,” said Markus Levy, president of EEMBC.
“Our EEMBC results confirm that the LPC1700 series is now the fastest and most efficient Cortex-M3 available in the market,” said Geoff Lees, vice president and general manager, microcontroller product line, NXP Semiconductors.
In the pipeline is a version with 512kbyte of flash memory.
