Arm has plan to make $1 Cortex-M processors secure Richard Wilson, Electronics Weekly, Dec. 08, 2015 –
The next generation Cortex-M series microcontroller, likely to be the Cortex-M5, will incorporate a version of Arm's TrustZone security technology, which creates highly secure processing elements within the chip.
TrustZone creates two modes of operation, one for standard operating systems, the other for the trusted tasks, including booting the system.
