Texas Instruments LM3S600 Block Diagram

TI's LM3S600 Series of Stellaris ARM Cortex-M3 microcontrollers target embedded control applications requiring more sophisticated algorithms such as motion control, medical instrumentation, HVAC and building control, factory automation, transportation, remote monitoring, electronic point-of-sale machines, network appliances and switches, and gaming equipment.

The TI Stellaris family of microcontrollers are based on the ARM Cortex-M3 v7-M processor; the microcontroller member of the ARM Cortex processor family. The Stellaris family provides entry into the ARM ecosystem. At the heart of the Cortex-M3 processor is an advanced 3-stage pipeline core, based on the Harvard architecture, incorporating features such as branch speculation, single cycle multiply and hardware divide.

Cortex-M3 implements the Thumb-2 instruction set architecture, helping it to be 70 percent more efficient per MHz than an ARM7TDMI-S processor executing Thumb instructions, and 35 percent more efficient than the ARM7TDMI-S processor executing ARM instructions, for the Dhrystone benchmark. Cortex-M3 uses a simplified stack-based programmer's model that maintains compatibility with traditional ARM architecture but is analogous to systems employed by legacy 8- and 16-bit architectures.
