An apparatus to implement an IP independent secure firmware load into an IP agent without a ROM to establish hardware root of trust is disclosed. The apparatus includes a plurality of agents, at least one agent including an isolated memory region accessible only to a trusted entity of the at least one agent and a main memory, and a processor to allocate a section of the isolated memory region 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, place the first stage firmware module into memory of the at least one agent without a ROM to establish the hardware root of trust. 公开了一种在没有ROM的情况下实现将IP独立的安全固件加载到IP代理中以建立硬件信任根的设备。该设备包括：多个代理，至少一个代理包括：仅对该至少一个代理的可信实体可访问的隔离存储器区域；以及主存储器；以及处理器，用于分配至少一个代理的隔离存储器区域的区段，验证第一级固件模块，该第一级固件模块包括指令，以使至少一个代理能够加载并验证第二级固件模块，在没有ROM的情况下将第一级固件模块放置到至少一个代理的存储器中,以建立硬件信任根。
