Silicon Labs (Energy Micro) Wonder Gecko STK Board with EFM32WG990 TI Stellaris Launchpad Board with LM4F120. Conceptually the Cortex-M4 is a Cortex-M3 plus DSP instructions, and optional floating-point unit (FPU). A core with an FPU is known as Cortex-M4F. Key features of the Cortex-M4 core are: [21] ARMv7E-M architecture [15]
This is a table of 64/32-bit central processing units that implement the ARMv8-A instruction set architecture and mandatory or optional extensions of it. Most chips support the 32-bit ARMv7-A for legacy applications.

IDE, compiler, linker, debugger, flashing (in alphabetical order): Ac6 System Workbench for STM32 [note 1] [1] [2] (based on Eclipse and the GNU GCC toolchain with direct support for all ST-provided evaluation boards, Eval, Discovery and Nucleo, debug with ST-LINK)
While Arm is a fabless semiconductor company (it does not manufacture or sell its own chips), it licenses the ARM architecture family design to a variety of companies. Those companies in turn sell billions of ARM-based chips per year—12 billion ARM-based chips shipped in 2014, [1] about 24 billion ARM-based chips shipped in 2020, [2] some of those are popular chips in their own right.
