Abstract: A computing system may implement a split random number generator that may use a random number generator to generate and store seed values in a memory for retrieval and use by one or more core processors to generate random numbers for secure processes within each core processor.

Abstract: Embodiments herein provide for improved store-to-load-forwarding (STLF) logic and linear aliasing effect reduction logic. In one embodiment, a load instruction to be executed is selected. Whether a first linear address associated with said load instruction matches a linear address of a store instruction of a plurality of store instructions in a queue is determined. Data associated with said store instruction for executing said load instruction is forwarded, in response to determining that the first linear address matches the linear address of the store instruction.

Abstract: The present invention provides a method and apparatus for allocating store queue entries to store instructions for early store-to-load forwarding. Some embodiments of the method include allocating an entry in a store queue to a store instruction in response to the store instruction being dispatched and prior to receiving a translation of a virtual address to a physical address associated with the store instruction. The entry includes storage for data to be written to the physical address by the store instruction.

Abstract: A method includes establishing an isolated execution environment for executing a platform firmware operating mode subroutine in a platform firmware operating mode. In response to receiving an interrupt, the platform firmware operating mode subroutine is executed in the isolated execution environment. In response to detecting an attempted access of a hardware resource resulting from execution of the platform firmware operating mode subroutine, the attempted access is blocked when the attempted access violates a security policy.
