ARM CMSIS 4.3.0 Software Pack Update

The CMSIS 4.3.0 Software Pack adds CMSIS-Driver for Serial Audio Interface (SAI) and improves CMSIS-RTOS RTX with Stack Watermark and IRQ timing statistics. Included are also several other enhancements such as cache control functions for Cortex-M7.

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

The CMSIS is defined in close cooperation with various silicon and software vendors and provides a common approach to interface to peripherals, real-time operating systems, and middleware components. The CMSIS is intended to enable the combination of software components from multiple middleware vendors.
