The THUMB instruction set formats are shown in the following figure. . All instructions in this format have an equivalent ARM instruction as shown in ·Table. Cortex M4 vs. M3. (b) The Cortex-M4 ISA is enhanced efficient DSP features including .. but Cortex-M3 supports only the 16-bit/32-bit Thumb-2 instruction set11 Jun 2018 The Cortex-M architectures only implement the Thumb instruction set - ARMv7-M (Cortex-M3/M4/M7) supports most of "Thumb-2 Technology", including ARM and Thumb-2 Instruction Set.
