The library is freely available as part of the CMSIS release from Arm and includes all source code The Arm Cortex-M4 processor implements a good blend of control and performance for mixed-signal devices. ARM's developer website includes documentation, tutorials, support resources and more. Over the next few months we will be adding more developer resources and documentation for all the products and technologies that ARM provides module integrated into the Cortex-M4. SWV is output on the Serial Wire Output (SWO) pin found on the JTAG adapter. SWV is output on the Serial Wire Output (SWO) pin found on the JTAG adapter. SWV does not steal any CPU cycles and is completely non-intrusive.(except for ITM Debug printf Viewer) Introduction .

The Cortex-M4 processor features extended single-cycle multiply-accumulate (MAC) instructions, optimized SIMD arithmetic, saturating arithmetic instructions and an optional single precision Floating Point Unit (FPU) As you maybe know, STM32F4 is Cortex M4 with DSP instructions. This allows you to make a FFT with a few simple steps. For that purpose, I have made an example, on how to create FFT with STM32F4. This allows you to make a FFT with a few simple steps They're in charge of the cortex-m4 and know know the capabilities which is fast enough to replace many of the traditional DSP processors for many kinds of applications. In addition to the processing power, the Cortex-M4 offers connectivity and certain devices have equally competitive power consumption as a traditional low powered DSP And one big thing around ARM is CMSIS (Cortex Microcontroller Software Interface Standard). It is an industry wide software library for the ARM Cortex microcontroller. Using the CMSIS It is an industry wide software library for the ARM Cortex microcontroller
