Luminary Micro, with the Stellaris family of ARM Cortex-M3-based microcontrollers (MCUs), supports ARM’s Cortex Microcontroller Software Interface Standard (CMSIS), a standardized hardware abstraction layer for the Cortex-M processor series. The purpose of the CMSIS initiative is precisely the same as Luminary Micro’s purpose when creating the Stellaris family of ARM Cortex-M3-based microcontrollers: to standardize a fragmented industry on one superior hardware and software microcontroller architecture.

The CMSIS enables consistent and simple software interfaces to the processor for silicon vendors and middleware providers, simplifying software re-use, reducing the learning curve for new microcontroller developers and reducing the time to market for new devices.
