Processor and operating method for a homogeneous dual computing system

Abstract

A processor for building a homogeneous dual computing system is shown. The processor provides two homogeneous cores. One is used as a trusted core and the other is used as a master core. The trusted core has an access right to an isolated storage space of a system memory. The master core is a normal core that is prohibited from accessing the isolated storage space. The trusted core has a first cryptographic module. In response to a reset of the trusted core, the first cryptographic module operates for firmware verification. This is how the trusted core turns on the processor using trusted firmware.
