 Hello, and welcome to this presentation of the ARM Cortex-M4 Core. In addition to the main Cortex-M4 CPU, the STM32WB microcontroller embeds a Cortex-M0 Plus Core. The Cortex-M4 Core benefits from the powerful performance of its 32-bit processor architecture and particularly high level of deterministic processing while the Cortex-M0 Plus Core manages the real-time radio operations. Based on the ARM Cortex-M4 Core, the STM32WB series doubles the DSP capability of a single-cycle DSP Mac for data processing and the single-precision FPU performance. In addition to the radio control capability offered by the ARM Cortex-M0 Plus Core, the STM32WB offers more control performance and enhanced execution determinism. Many application domains can benefit from the dual-core architecture of the STM32WB devices. The Cortex-M4 in the STM32WB 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. For more details, please refer to the ARM website in which you will find all the information about the Core Cortex-M4.
