ARM® Cortex®-M4 with FPU
ARM's Ultra-Low-Power DSP Class Processor
The ARM Cortex-M4 processor is an award winning processor specifically developed to address digital signal control markets that demand an efficient, easy-to-use blend of control and signal processing capabilities. EFM32™ MCUs combine high-efficiency signal processing functionality with the proven energy friendly Gecko technology, making these devices ideal for lower energy applications.
Cortex-M4 with FPU and Signal Processing Technologies
The Cortex-M4 processor has been designed with a large variety of highly efficient signal processing features applicable to digital signal control markets. The processor features extended single-cycle multiply-accumulate (MAC) instructions, optimized SIMD arithmetic, saturating arithmetic instructions and an optional single precision Floating Point Unit (FPU). These features build upon the innovative technology that characterizes the ARM Cortex-M series processors.
- IEEE 754 standard compliant
- Single precision floating point unit
- Fused MAC for higher precision
