5.3 ARM Cortex-M4 Processor Core Subsystem
The high-performance ARM Cortex-M4 processor provides a low-cost platform that meets the needs of
minimal memory implementation, reduced pin count, and low power consumption, while delivering
outstanding computational performance and exceptional system response to interrupts.
• The ARM Cortex-M4 core has low-latency interrupt processing with the following features:
– A 32-bit ARM Cortex Thumb® instruction set optimized for embedded applications
– Handler and thread modes
– Low-latency interrupt handling by automatic processor state saving and restoration during entry and
exit
– Support for ARMv6 unaligned accesses
