  • Patent number: 11249926
    Abstract: A peripheral device implements a plurality of queue sets each including a submission queue and a completion queue. Changes to the queues are monitored and arbitration parameters are adjusted, the arbitration parameters defining how submission queues are selected for retrieval of a command. An arbitration burst for a submission queue may be increased in response to tail movement for the submission queue being larger than for another submission queue. Priorities used for weighted round robin arbitration may also be adjusted based on tail movement. Arbitration burst quantities and priorities of groups of queues may also be adjusted. Head movement of the completion queues is monitored and may be used to lower priority, enable interrupt coalescing, or pause command retrieval where head movement does not meet a threshold condition.

  • Patent number: 10902171
    Abstract: Systems and methods are disclosed for generation and testing of integrated circuit designs with clock crossings between clock domains. These may allow for the rapid design and testing (e.g. silicon testing) of processors and SoCs. Clock crossings may be automatically generated between modules, inferring the values of design parameters, such as a signaling protocol (e.g. a bus protocol), directionality, and/or a clock crossing type (e.g., synchronous, rational divider, or asynchronous), of a clock crossing. For example, implicit classes may be used to generate clock crossings in a flexible manner. For example, these system and methods may be used to rapidly connect a custom processor design, including one or more IP cores, to a standard input/output shell for a SoC design to facilitate rapid silicon testing of the custom processor design.

  • Patent number: 10789194
    Abstract: Systems and techniques for synchronizing transactions between processing devices on an interconnection network are provided. Upon receiving a stream of posted transactions followed by a flush transaction from a source processing device connected to the interconnection network, the flush transaction is trapped before it enters the interconnecting network. Subsequently, based on monitoring for responses received from a destination processing device for transactions corresponding to the posted transactions, a flush response is generated and returned to the source processing device. The described techniques enable efficient synchronizing posted writes, posted atomics and the like over complex interconnection fabrics such that a first GPU can write data to a second GPU so that a third GPU can safely consume the data written to the second GPU.

  • Patent number: 10430230
    Abstract: The use of a skip element when redoing transactions, so as to avoid tracking dependencies between transactions assigned to different threads for parallel processing. When the second thread comes to a second task in the course of redoing a second transaction, if a first task that is mooted by the second task is not already performed, the second thread inserts a skip element associated with the object to be operated upon by the particular task, instead of actually performing the particular task upon the object. When the first thread later comes to the first task in the course of redoing a first transaction, the first thread encounters the skip element associated with the object. Accordingly, instead of performing the dependee task, the first thread skips the dependee task and perhaps removes the skip element. The result is the same regardless of whether the first or second task is redone first.

  • Patent number: 10324875
    Abstract: Provided are a data processor, and a control system, in which an interrupt controller and an event link controller are adopted. The event link controller responds to a generated event signal to output a start control signal for controlling start of an operation of a circuit module. The circuit module is able to generate an event signal. The event link controller generates the start control signal according to the correspondences between event signals and start control signals which are defined by event control information. The links between the event signals and start control signals can be prescribed by the event control information. Therefore, operations of circuit modules prescribed by such links can be controlled sequentially. The control neither involves save and return processes by CPU as in the interrupt processing, nor needs priority level control as executed on competing interrupt requests.

    Abstract: In a memory system in which a system clock signal is forwarded from the memory controller to multiple memory devices, the phase of the system clock signal forwarded to the slower memory device is advanced relative to the system clock signal forwarded to the faster memory device by a phase corresponding to the skew on the data links corresponding to the memory devices. This causes the state machine of the slower memory device to change states and advance earlier than the state machine in the faster memory device, and as a result, the data read from both the slower memory device and the faster memory device are unskewed on the data links between the memory controller and the memory devices.

  • Patent number: 9134356
    Abstract: In processing devices, in particular in measuring, test or control units for the drivetrain or components thereof, it is often necessary to combine signals or data of different synchronization sources with one another or to process them whilst maintaining the original temporal relation. In order to achieve this, the signals or data have hitherto often been synchronized to a specific clock source, but this is frequently not possible. Therefore, a method and a device are specified which enable the processing of data or signals with different synchronization sources in a processing device by virtue of the fact that a dedicated time level is introduced for each synchronization source in the processing device, the temporal reference of the associated data and signals being retained in the time levels. The signals and data are processed in the time levels with the temporal original reference being maintained.

  • Patent number: 9092160
    Abstract: Selective enablement of operating modes or features of a storage system via host transfer rate detection enables, in some situations, enhanced performance. For example, a Solid-State Disk (SSD) having a serial interface compatible with a particular serial interface standard selectively enables coalescing of status information for return to a host based on detecting a particular host transfer rate capability. Some hosts are not fully compliant with the particular standard, being unable to properly process the coalesced status information. The selective enablement disables status coalescing for a non-compliant host and enables status coalescing for at least some compliant hosts, without the SSD having prior knowledge of coupling to a noncompliant/compliant host. The SSD conservatively determines the host is non-compliant/compliant based on a negotiated speed of the serial interface, and selectively disables/enables status coalescing in response to the negotiated speed.

  • Patent number: 9015381
    Abstract: A method is described that involves detecting the presence of a pairing partner. Prior to establishing a paired relationship with the pairing partner, a user is prompted to verify himself/herself. In response to the user properly verifying himself/herself, the paring partner is paired with. The pairing includes invoking a remote storage protocol that contemplates a network between the partners to establish on a first of the partners access to non volatile storage resources for general use. The non volatile storage resources are located on a second of the partners. The second of the partners is a handheld device that provides wireless cell phone service, wireless Internet service and music playback service.

  • Patent number: 9009378
    Abstract: A system for enhancing universal serial bus (USB) applications comprises an upstream processor, a downstream processor and a main controller. The upstream processor accepts standard USB signals from a USB host and independently provides responses required by USB specification within the required time frame. The upstream processor also contains storage for descriptors for a device associated with this upstream processor. The main controller obtains the descriptors by commanding the downstream processor, and passes them to the upstream processor. The downstream processor connectable to USB-compliant devices accepts the USB signals from the USB-compliant devices and provides responses required by USB specification within the required time frame. The main controller interconnects the upstream and downstream processors, and provides timing independence between upstream and downstream timing. The main controller also commands the downstream processor to obtain device descriptors independent of the USB host.
