G06F 9/00
G06F 9/44
G06F 15/00

US Classification:

712244

Abstract:

According to a first aspect, efficient data transfer operations can be achieved by: decoding by a processor device, a single instruction specifying a transfer operation for a plurality of data elements between a first storage location and a second storage location; issuing the single instruction for execution by an execution unit in the processor; detecting an occurrence of an exception during execution of the single instruction; and in response to the exception, delivering pending traps or interrupts to an exception handler prior to delivering the exception.

International Classification:

G06F 21/60
H04L 9/08
H04L 9/30

Abstract:

Embodiments for dynamically mitigating speculation vulnerabilities are disclosed. In an embodiment, an apparatus includes a hybrid key generator and memory protection hardware. The hybrid key generator is to generate a hybrid key based on a public key and multiple process identifiers. Each of the process identifiers corresponds to one or more memory spaces in a memory. The memory protection hardware is to use the first hybrid key to protect to the memory spaces.

International Classification:

G06F 9/48
G06F 9/54
G06F 9/30

Abstract:

Processors, methods, and systems for user-level interprocessor interrupts are described. In an embodiment, a processing system includes a memory and a processing core. The memory is to store an interrupt control data structure associated with a first application being executed by the processing system. The processing core includes an instruction decoder to decode a first instruction, invoked by a second application, to send an interprocessor interrupt to the first application; and, in response to the decoded instruction, is to determine that an identifier of the interprocessor interrupt matches a notification interrupt vector associated with the first application; set, in the interrupt control data structure, a pending interrupt flag corresponding to an identifier of the interprocessor interrupt; and invoke an interrupt handler for the interprocessor interrupt identified by the interrupt control data structure.

International Classification:

G06F 3/06
G06F 9/30

Abstract:

Processor, method, and system for reducing latency in accessing remote registers is described herein. One embodiment of a processor includes one or more remote registers and remote register access circuitry. The remote register access circuitry is to detect a request from the requestor to access a first register of the one or more remote registers, access to the first register in accordance to the request without the requestor having to wait for completion of the access, and provide a notification accessible to the requestor upon completion of the access to the first register of the one or more remote registers.
