Digital signal control capabilities on TI’s Stellaris ARM Cortex™-M4F core based microcontrollers highlighted by software interface standard

Developers can now migrate existing CMSIS-based software to any Stellaris microcontroller and make the switch to TI

Enabling developers to streamline the design process, Texas Instruments Incorporated (TI) has announced its Stellaris® Cortex™-M4F-core based microcontrollers (MCUs) now support ARM’s® latest Cortex Microcontroller Software Interface Standard (CMSIS). In addition to TI’s StellarisWare® software suite, ARM’s CMSIS libraries help developers realize the industry-leading benefits of Stellaris LM4F microcontrollers by simplifying the implementation of floating point, single instruction multiple data (SIMD) and digital signal processing (DSP) operations.

Stellaris MCUs are the industry’s leading family of 32-bit microcontrollers based on the ARM Cortex-M core. The Stellaris LM4F (Cortex-M4F) series of microcontrollers delivers leading analog integration, floating-point performance, best-in-class low power and are ideal for a variety of applications including scanners, microprinters, home/building automation, AC inverter drives and uninterruptible power supplies. Stellaris MCUs include TI’s free StellarisWare software, which eases development and speeds time-to-market with code and royalty-free libraries for application support. The software suite includes the Stellaris Peripheral Driver library, Stellaris USB library, Stellaris Graphics library and Stellaris Boot Loader – all pre-programmed in ROM on Stellaris MCUs.

Features and benefits

• A standardized software interface allows developers to make the switch from a competitive MCU to TI’s Stellaris microcontrollers and more easily migrate existing software to any Stellaris LM4F microcontroller.

• CMSIS DSP library includes source code, example applications and helps developers save time by including common DSP algorithms like complex arithmetic, vector operations, filter and control functions, etc.

• ARM’s Cortex-M4F core uses DSP SIMD instruction set and floating-point hardware that enhances Stellaris LM4F microcontrollers’ algorithm capabilities for digital signal control applications
