  • Publication number: 20250094567
    Abstract: In an embodiment, a processor includes hardware circuitry which may be used to authenticate instruction operands. The processor may execute instructions that perform operand authentication both speculatively and non-speculatively. During speculative execution of such instructions, the processor may execute authentication such that no differences in observable state of the processor, relative to authentication result, are detectable via a side channel. During speculative execution, a result of authentication may be deferred until speculative execution of the instruction, and additional instructions, may be completed. Upon resolution of a condition that indicates acceptance of the speculative execution, a speculative execution result may cause a processor exception and stalling of execution at the instruction to be performed.

  • Publication number: 20240311319
    Abstract: An interrupt delivery mechanism for a system includes and interrupt controller and a plurality of cluster interrupt controllers coupled to respective pluralities of processors in an embodiment. The interrupt controller may serially transmit an interrupt request to respective cluster interrupt controllers, which may acknowledge (Ack) or non-acknowledge (Nack) the interrupt based on attempting to deliver the interrupt to processors to which the cluster interrupt controller is coupled. In a soft iteration, the cluster interrupt controller may attempt to deliver the interrupt to processors that are powered on, without attempting to power on processors that are powered off. If the soft iteration does not result in an Ack response from one of the plurality of cluster interrupt controllers, a hard iteration may be performed in which the powered-off processors may be powered on.

  • Publication number: 20230333851
    Abstract: Techniques are disclosed relating to data synchronization barrier operations. A system includes a first processor that may receive a data barrier operation request from a second processor include in the system. Based on receiving that data barrier operation request from the second processor, the first processor may ensure that outstanding load/store operations executed by the first processor that are directed to addresses outside of an exclusion region have been completed. The first processor may respond to the second processor that the data barrier operation request is complete at the first processor, even in the case that one or more load/store operations that are directed to addresses within the exclusion region are outstanding and not complete when the first processor responds that the data barrier operation request is complete.

  • Patent number: 11422821
    Abstract: A system and method for efficiently handling instruction execution ordering. In various embodiments, a processor includes multiple execution lanes, each executing instructions of a particular type, which are not executed by one or more of the other execution lanes. The instruction queue includes one queue for each particular execution lane. Control logic identifies a current youngest age used in allocated entries of the multiple queues, and determines a starting age based on the identified current youngest age and the number of instructions to be issued. Beginning with the determined starting age, ages (in program order) are assigned to a group of instructions being allocated in the multiple queues. Ages of entries in the multiple queues are updated for instructions not being issued based on the number of instructions being issued. Instructions being issued have age differences between them below a threshold.

  • Patent number: 11264099
    Abstract: An example apparatus includes a controller and a memory device. The memory device is configured to maintain, internal to the memory device, a status of a number of open blocks in the memory device. The status can include a programming operation being initiated in the respective number of open blocks. Responsive to receipt of, from the controller, a request to direct initiation of the programming operation to a word line, determine a group of memory cells associated with the word line that programs first relative to other groups of memory cells associated with the word line and maintain, included in the status of an open block, a voltage at which the group of memory cells is the first group to program.
