  • Arm Cortex-M4
    • SIMD, saturating arithmetic, fast MAC - Powerful instruction set for accelerating DSP applications, built right into the processor. A highly optimised DSP library built using these instructions is available free-of-charge from the Arm website.
    • Powerful debug and non-obtrusive real-time trace - Comprehensive debug and trace features dramatically improve developer productivity. It is extremely efficient to develop embedded software with proper debug.
    • Memory Protection Unit (MPU) - Software reliability improves when each module is allowed access only to specific areas of memory required for it to operate. This protection prevents unexpected access that may overwrite critical data.
    • Integrated nested vectored interrupt controller (NVIC) - There is no need for a standalone external interrupt controller. Interrupt handling is taken care of by the NVIC removing the complexity of managing interrupts manually via the processor.
