Abstract: A processor for building a homogeneous dual computing system is shown. The processor has a trusted core, a normal core, and a shared cache. The trusted core has an access right to an isolated storage space of a system memory. The normal core is homogeneous with the trusted core, and is prohibited from accessing the isolated storage space. In response to a cache flush instruction issued by the normal core, the trusted core initiates and executes a second cache write-back instruction that is different from the first cache write-back instruction. According to the second cache write-back instruction, isolated data associated with the isolated storage space and cached in the shared cache is written back to the isolated storage space before being flushed.

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.

Abstract: A trusted computing technology is shown. An isolated memory stores a security interrupt descriptor table (SIDT) to correspond to security interrupts triggered by security peripherals. A first register of the trusted core stores a first address pointing to the SIDT. A local advanced programmable interrupt controller in the trusted core provides an interrupt arbiter that arbitrates between peripheral interrupts received from the chipset. When producing an arbitration result showing that a target interrupt is a security interrupt, the interrupt arbiter outputs a security interrupt request and a security interrupt vector to trigger the trusted core to search the SIDT indicated by the first register, to get a target security interrupt descriptor for execution of the corresponding interrupt program.
