9.1.3 Cortex-M4F Processor Features and Configuration
- The Thumb instruction set combines high code density with 32-bit performance
- IEEE 754-compliant single-precision Floating Point Unit (FPU)
- Integrated sleep modes for low power consumption
- Fast code execution permits slower processor clock or increases Sleep mode time
- Hardware division and fast digital-signal-processing orientated multiply accumulate
- Saturating arithmetic for signal processing
- Deterministic, high-performance interrupt handling for time-critical applications
- Memory Protection Unit (MPU) for safety-critical applications
- Extensive debug and trace capabilities: Serial wire debug and serial wire trace reduce the number of pins required for debugging, tracing and code profiling.
