Non-ROM based IP firmware verification downloaded by host software

A processor-implemented method, comprising:

• allocating a section of an isolated memory region of the at least one agent of a plurality of agents, the isolated memory region accessible only to a trusted entity of the at least one agent;
• verifying a first stage firmware module, the first stage firmware module comprising instructions to enable the at least one agent to load and verify a second stage firmware module;
• providing the first stage firmware module to a memory of the at least one first agent without a ROM;
• programming a load interface register of the at least one agent with a memory address offset of the isolated memory region and a memory address offset of the verified first stage firmware and one or more public keys in the isolated memory region;
• and
• placing the second stage firmware module in a host memory accessible to the at least one agent.

At least one non-transitory computer readable medium having instructions stored thereon, which when executed by a processor, cause the processor to:

• allocate a section of an isolated memory region of the at least one agent of a plurality of agents, the isolated memory region accessible only to a trusted entity of the at least one agent;
• verify a first stage firmware module, the first stage firmware module comprising instructions to enable the at least one agent to load and verify a second stage firmware module;
• provide the first stage firmware module to a memory of the at least one first agent without a ROM;
• program a load interface register of the at least one agent with a memory address offset of the isolated memory region and a memory address offset of the verified first stage firmware and one or more public keys in the isolated memory region;
• and
• place the second stage firmware module in a host memory accessible to the at least one agent.
