TXE)
Intel
®
TXE is a security co-processor used to enable security features.
See
Chapter 17, “Intel
®
Trusted Execution Engine (TXE)”
for more details.
Security features include:
•
Isolated execution environment for crypto operations (SKU-enabled)
•
Supports secure boot - with customer programmable keys to secure code
Note:
The SoC requires TXE firmware in the PCU SPI flash image to function. Contact your
