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

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
