Armv8 and Armv8-M processor already support Arm TrustZone security, which aims to prevent software attacks against the target device. However, if a hacker has physical access to the hardware, it may not be sufficient to prevent hacking. Arm Cortex-M35P core addresses this issue by providing physical (hence the P in the name) security with anti-tampering features that protect against access even with direct access to the hardware. Highlights of the processor: Architecture – Armv8-M Mainline (Harvard) ISA Support – Thumb/Thumb-2 Pipeline – Three-stage Software security – Optional TrustZone for Armv8-M, stack pointers checking Physical security – Built-in protection from invasive and non-invasive attacks DSP Extensions Optional DSP/SIMD instructions Single cycle 16/32-bit MAC Single cycle dual 16-bit MAC 8/16-bit SIMD arithmetic Floating Point Unit – Optional single precision floating point unit,IEEE 754 compliant Co-processor interface – Optional dedicated co-processor bus interface for up to 8 co-processor units for custom compute Memory […]
