Cortex Microcontroller Software Interface Standard

http://www.arm.com/cmsis

The ARM® Cortex™ Microcontroller Software Interface Standard (CMSIS) is a vendor-independent hardware abstraction layer for the Cortex-M processor series. The CMSIS enables consistent and simple software interfaces to the processor and the peripherals, simplifying software re-use, reducing the learning curve for new microcontroller developers and reducing the time to market for new devices.

The CMSIS consists of the following components:

• CMSIS-CORE: provides an interface to Cortex-M0, Cortex-M3, Cortex-M4, SC000, and SC300 processors and peripheral registers
• CMSIS-DSP: DSP library with over 60 functions in fixed-point (fractional q7, q15, q31) and single precision floating-point (32-bit) implementation
• CMSIS-RTOS API: standardized programming interface for real-time operating systems for thread control, resource, and time management
• CMSIS-SVD: System View Description XML files that contain the programmer’s view of a complete microcontroller system including peripherals
