ARM Cortex-M4 Processor Microarchitecture

►Backwards compatible with ARM Cortex-M3
►New features
• Single cycle MAC (Up to 32 x 32 32, with 32-bit 32 bit result)
• DSP extensions
• Single Precision Floating Point Unit
►Freescale IP and Innovation
• On-chip cache for instructions and data
• Cross-Bar Switch for concurrent multi-master/slave
accessing
• On-chip p DMA for CPU off-load
• Low-leakage Wake-up Unit adds flexibility for low power
operation
►Architected for Digital Signal Processing
• Motor Control - advanced algorithms, longer lifespan,
power efficiency
• Automation - high calculation and algorithm bandwidth
at a low cost
• Power management – designed for low/battery
powered systems
• Audio and Video – 5x performance improvement over
software, making batteries last longer
