Vote in the 'DSP Vs. CORTEX-M4 with dsp & fpu' poll on element14.com. Although the boundary between DSP & MCU is vanished still I want to here from you that what is your first choice when playing with digital signal.Is it a

Cortex-M4 and Cortex-M4F can do these operations more efficiently and fast compared to Cortex-M3. However, if you are using Cortex-M4 for applications which do not need DSP or FPU than using cortex-M4 instead of Cortex-M3 will give you no better results as the architecture of both of them are same.

The other key feature that separates Cortex-M4 processors from less advanced ones is the addition of a Floating Point Unit (FPU). An FPU is a separate processor Does the ARM core include an FPU? Cortex-M4F and Cortex-M7F cores do. How much Flash memory and RAM does the target device has? e.g. 256 KiB of Flash In order to get the most from the mikroC PRO for ARM compiler, the user should be familiar with certain aspects of ARM Cortex-M4 MCU. The Floating-Point Unit (FPU) fully supports single-precision add, subtract, multiply, divide, multi The extension ' +vfpv3-d16 ' can be used as an alias for this extension.

The Cortex-M4 FPU is an implementation of the single precision variant of the ARMv7-M Floating-Point Extension (FPv4-SP). It provides floating-point The Cortex-M architectural HAL provides support for a hardware Floating Point Unit (FPU) if one is present, to provide accelerated floating point math operations. The other key feature that separates Cortex-M4 processors from less advanced ones is the addition of a Floating Point Unit (FPU). An FPU is a separate processor Does the ARM core include an FPU?
