The Cortex-M3 / M4 / M7 / M33 / M35P have all base Thumb-1 and Thumb-2 instructions. The Cortex-M3 adds three Thumb-1 instructions, all Thumb-2 instructions, hardware integer divide, and saturation arithmetic instructions. The Cortex-M4 adds DSP instructions and an optional single-precision floating-point unit (VFPv4-SP). The Cortex-M7 adds an ...

Most of the Thumb instructions are directly mapped to normal ARM instructions. The space saving comes from making some of the instruction operands implicit and limiting the number of possibilities compared to the ARM instructions executed in the ARM instruction set state. In Thumb, the 16-bit opcodes have less functionality.
This is a list of central processing units based on the ARM family of instruction sets designed by ARM Ltd. and third parties, sorted by version of the ARM instruction set, release and name. In 2005, ARM provided a summary of the numerous vendors who implement ARM cores in their design. [ 1 ]
MK20DX128 32 bit ARM Cortex-M4 48 MHz [209] PJRC: A very small board based on the Freescale MK20DX128VLH5 CPU. It has 34 I/O pins; 16 KB RAM; 128 KB of flash; 16-bit ADC; 3xUARTs, SPI, I²C, I²S, Touch and other I/O capability. Version 3.0 is not recommended for new designs. Teensy 3.1/3.2 [212] MK20DX256 32 bit ARM Cortex-M4 72 MHz [209] PJRC
XMC is a family of microcontroller ICs by Infineon.The XMC microcontrollers use the 32-bit RISC ARM processor cores from ARM Holdings, such as Cortex-M4F and Cortex-M0.XMC stands for "cross-market microcontrollers", meaning that this family can cover due to compatibility and configuration options, a wide range in industrial applications.
The EFM32 family consists of several sub-families, ranging from the EFM32 Zero Gecko, [6] based on an ARM Cortex-M0+, [3] to the higher performing EFM32 Giant Gecko [7] and Wonder Gecko, [8] based on Cortex-M3 [4] and Cortex-M4 [5] respectively.
