ARM’s Cortex-M3 and Cortex-M4 have been very successful but there was a performance gap between the top end Cortex-M4 and the Cortex-A series. The new Cortex-M7 fills out their microcontroller line. It is code compatible with the Cortex-M4 but it offers improved performance and scalability. The Cortex-M7 adds features like code and data caches (Fig. 1) . Its low power and high performance are a combination that should fare well in a range of application areas like the Internet of Things (IoT) and wearable technology. The architecture employs a 6-stage superscalar pipeline. It also has branch prediction support. This allows it to deliver 5.04 CoreMark/MHz using a 40-nm process (Fig. 2) . The 28-nm node will allow performance to double. The Cortex-M7 supports the ARMv7-M instruction set. This includes bit manipulation instructions. It includes single cycle, DSP extensions us...
