Abstract: An apparatus to verify firmware in a computing system, comprising a non-volatile memory, including firmware memory to store agent firmware associated with each of a plurality of interconnect protocol (IP) agents and version memory to store security version numbers (SVNs) included in the agent firmware, a security controller comprising verifier logic to verify an integrity of the version memory by applying a hash algorithm to contents of the version memory to generate a SVN hash, and a trusted platform module (TPM) to store the SVN hash.

Abstract: An example system on a chip (SoC) includes a processor, a cache, and a main memory. The processor can receive a data packet from an electronic device via an interface device, the data packet comprising data for an offload processing task, where the data packet is in a standard link protocol format, the standard link protocol format comprising at least one of an offload protocol identification (ID) field, a tag field, a returned data length field, a flag field, a reserved field, a length field, or a data field. The processor can process the offload processing task to obtain result data. The processor can send the result data to the electronic device.
