 Hello, and welcome to this presentation of the ARM Cortex-M4 Core. In addition to the main Cortex-M7 CPU, the STM32-H747-H757 and STM32-H745-H755 microcontrollers integrate a Cortex-M4 Core in order to benefit from the powerful performance of the 32-bit processor architecture, and particularly of the high level of deterministic processing. Based on the ARM Cortex-M4 Core, the STM32-H7 series doubles the DSP capability of a single-cycle DSP Mac for data processing and the single-precision FPU performance. In addition to the computation capability offered by the ARM Cortex-M7 Core, the STM32-H7 offers more control, performance, and enhanced execution determinism. Many application domains can benefit from the dual-core architecture of the STM32-H745-755-747-757 devices. The Cortex-M4 in the STM32-H7 microcontroller offers support for eight independent memory regions with independent configurable attributes for access permission, read-write allowed or not in privileged, unprivileged mode, execution permission, executable region or region prohibited for instruction fetch, and cache policies that affect art accelerator instruction cache behavior.
