The Cortex-M7 processor's industry leading high-performance and flexible system interfaces are ideal for a wide variety of application areas.
Image and video processing
Advanced motor control
Optional instruction and data TCMs up to 16MB
Fast access to critical code and data via a dedicated bus. Increases responsiveness to critical events.
Harvard instruction cache and data cache on 64-bit AMBA 4 AXI interface
Optimises access to large external memories or slow peripherals, reducing latency. Instruction and data caches are optional and separately configurable from 4KB to 64KB.
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, with optional full data 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 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.

** The first result abides by all of the “ground rules” laid out in the Dhrystone documentation, the second permits inlining of functions, not just the permitted C string libraries, while the third additionally permits simultaneous (”multi-file”) compilation. All are with the original (K&R) v2.1 of Dhrystone.
*** Base usable configuration includes 1 IRQ + NMI, excludes ETM, MPU, FPU and debug.
