Abstract: An electronic device includes a quantum processor including a plurality of qubits. The quantum processor runs a plurality of instances of a quantum program using a separate set of qubits from among the qubits for each instance of the quantum program. The quantum processor then sets quantum states for ancilla qubits from among the qubits based on quantum states of respective groups of associated qubits from the separate sets of qubits. The quantum processor next provides an output of the instances of the quantum program based on the quantum states of the ancilla qubits.

Abstract: A processor distributes memory timing parameters and data among different memory modules based upon memory access patterns. The memory access patterns indicate different types, or classes, of data for an executing workload, with each class associated with different memory access characteristics, such as different row buffer hit rate levels, different frequencies of access, different criticalities, and the like. The processor assigns each memory module to a data class and sets the memory timing parameters for each memory module according to the module's assigned data class, thereby tailoring the memory timing parameters for efficient access of the corresponding data.

Abstract: The described embodiments include a computing device with two or more translation lookaside buffers (TLB). During operation, the computing device updates an entry in the TLB based on a virtual address to physical address translation and metadata from a page table entry that were acquired during a page table walk. The computing device then computes, based on a lease length expression, a lease length for the entry in the TLB. Next, the computing device sets, for the entry in the TLB, a lease value to the lease length, wherein the lease value represents a time until a lease for the entry in the TLB expires, wherein the entry in the TLB is invalid when the associated lease has expired. The computing device then uses the lease value to control operations that are allowed to be performed using information from the entry in the TLB.

Abstract: A dynamically configurable overprovisioned microprocessor optimally supports a variety of different compute application workloads and with the capability to tradeoff among compute performance, energy consumption, and clock frequency on a per-compute application basis, using general-purpose microprocessor designs. In some embodiments, the overprovisioned microprocessor comprises a physical compute resource and a dynamic configuration logic configured to: detect an activation-warranting operating condition; undarken the physical compute resource responsive to detecting the activation-warranting operating condition; detect a configuration-warranting operating condition; and configure the overprovisioned microprocessor to use the undarkened physical compute resource responsive to detecting the configuration-warranting operating condition.

Abstract: An approach for tracking data stored in caches uses a Bloom filter to reduce the number of addresses that need to be tracked by a coherence directory. When a requested address is determined to not be currently tracked by either the coherence directory or the Bloom filter, tracking of the address is initiated in the Bloom filter, but not in the coherence directory. Initiating tracking of the address in the Bloom filter includes setting hash bits in the Bloom filter so that subsequent requests for the address will “hit” the Bloom filter. When a requested address is determined to be tracked by the coherence directory, the Bloom filter is not used to track the address.

Abstract: An electronic device includes a quantum processor having a plurality of qubits and a processor. The processor runs a plurality of instances of a quantum program substantially in parallel on the quantum processor using a separate set of qubits from among the plurality of qubits for each instance of the quantum program. The processor then acquires an output for each instance of the quantum program from the quantum processor. The processor next uses the outputs for generating an output of the quantum program.

Abstract: The described embodiments include a computing device with two or more translation lookaside buffers (TLB) that performs operations for handling entries in the TLBs. During operation, the computing device maintains lease values for entries in the TLBs, the lease values representing times until leases for the entries expire, wherein a given entry in the TLB is invalid when the associated lease has expired. The computing device uses the lease value to control operations that are allowed to be performed using information from the entries in the TLBs. In addition, the computing device maintains, in a page table, longest lease values for page table entries indicating when corresponding longest leases for entries in TLBs expire. The longest lease values are used to determine when and if a TLB shootdown is to be performed.
