Abstract
A computing system includes a first central processing unit (CPU) and a second CPU coupled with the first CPU and with a host processor. In response to a request by the host processor to boot the second CPU, the first CPU is configured to execute secure booting of the second CPU by decrypting encrypted code to generate decrypted code executable by the second CPU but that is inaccessible by the host processor.
