The hack stems from the fact that the Serial Wire Debug or SWD interface cannot be completely disabled on these chips even if the Memory Protection Unit prevents access to any memory regions directly.

In similar sense, the tiny microcontrollers inside our devices have protection units (PU) that safeguard the precious resource: memory. One of the most important types of protection units is the ...

Earlier Cortex R-series processors weren't capable of running full-fledged modern operating systems, including Linux, because they utilized a simple Memory Protection Unit (MPU) rather than the ...

This is where the MPU (Memory Protection Unit) gets abused. Usually, a write to 0x10xxxxxx will flush the cache line. When a write happens, the MPU can trigger a hard fault by marking that region ...

A memory management unit (MMU) also offers memory protection by organizing the memory into pages of a fixed size. This not only can support virtual memory, ...

G.SKILL Unveils Newly Enhanced DDR5 R-DIMM Memory with 16-Layer PCB for Improved Signal Integrity and Enhanced Voltage Protection via Two Transient Voltage Suppression Diodes and a Fuse ...

The new Android 14 feature enables Memory Tagging Extension on compatible ArmV8.5+ devices. The Pixel 7 and 7 Pro feature the Tensor G2 chip that consists of ArmV8.2 CPU cores (Cortex X1, Cortex ...

uC/OS-MMU offers memory protection for central processing units (CPUs) that incorporate a memory management unit (MMU) giving them time and space protection for multiple independent applications.

The protection-domain memory model allows code and data resources to be encapsulated in a protected environment.

OpenRTOS adds memory protection to Cortex-M3. Wittenstein High Integrity Systems has announced an integrated memory protection unit (MPU) support for Cortex-M3 microcontrollers in its OpenRTOS kernel.
