Renesas adds more DSP to low power IoT MCUs

by Richard Wilson - Electronics Weekly, Jul. 01, 2015 – 

Renesas Electronics has introduced a low power microcontroller with DSP extensions and a floating point unit (FPU) in its RX series.

The RX231 32-bit microcontrollers are based on a new version of the RX CPU core with a performance benchmark score of 4.16 CoreMark/MHz, which is a 35% increase on the previous generation RX200 series.

With operating speeds of 54MHz, there is an approximate increases of up to x4 in DSP performance and x6 in FPU performance, which will help in digital filtering applications.
