DEBUG FUNCTIONALITY IN A SECURE COMPUTING ENVIRONMENT |
| 摘要 |
A computer system includes a security processor, a first scan chain coupled to the security processor, a non-secure element, and a second scan chain coupled to the non-secure element. The computer system also includes one or more test access port controllers to control operation of the first and second scan chains, and further includes debug control logic, coupled to the one or more test access port controllers, to enable the one or more test access port controllers to activate debug functionality on the second scan chain but not the first scan chain in response to a predefined condition being satisfied. |
