Semiconductor apparatus
An object is to obtain output data corresponding to input data by referring to table data by a semiconductor apparatus having a simple configuration. An MCU includes a DTC for transferring data from a source address region to a destination address region based on data transfer information in response to a startup request. The DTC performs an operation on second source address information based on data that has been read from first source address information, performs reading based on a result of the operation, and writes read data based on destination address information.
Determining when to throttle interrupts to limit interrupt processing to an interrupt processing time period
Provided are a computer program product, system, and method for determining when to throttle interrupts to limit interrupt processing to an interrupt processing time. Upon receiving interrupts from the hardware device, a determination is made as to whether a number of received interrupts exceeds an interrupt threshold during a interrupt tracking time period. If so, an interrupt throttling state is set to a first value indicating to only process interrupts during an interrupt processing time period. Interrupts from the hardware device are processed during the interrupt time period when the interrupt throttling state is set to the first value. Interrupts received from the hardware are masked during a processing of a scan loop of operations while the interrupt throttling has the first value and the interrupt processing time period has expired, wherein the masked interrupts are not processed while processing the scan loop of operations.
SYNCHRONIZATION OF INTERRUPT PROCESSING TO REDUCE POWER CONSUMPTION
A processor is disclosed and includes at least one core including a first core, and interrupt delay logic. The interrupt delay logic is to receive a first interrupt at a first time and delay the first interrupt from being processed by a first time delay that begins at the first time, unless the first interrupt is pending at a second time when a second interrupt is processed by the first core. If the first interrupt is pending at the second time, the interrupt delay logic is to indicate to the first core to begin to process the first interrupt prior to completion of the first time delay. Other embodiments are disclosed and claimed.
Host polling of a network adapter
Embodiments herein describe a host that polls a network adapter to receive data from a network. That is, the host/CPU/application thread polls the network adapter (e.g., the network card, NIC, or SmartNIC) to determine whether a packet has been received. If so, the host informs the network adapter to store the packet (or a portion of the packet) in a CPU register. If the requested data has not yet been received by the network adapter from the network, the network adapter can delay the responding to the request to provide extra time for the adapter to receive the data from the network.
NETWORK CONTROLLER AND NETWORK CONTROL METHOD
A network controller includes a data check circuit and an interrupt controller circuit. The data check circuit verifies whether multiple packets are valid. The interrupt controller circuit counts according to a first packet in the multiple packets when the first packet is valid to generate a first count value, and issues an interrupt signal to a processor when the first count is equal to a first predetermined value.
HOST POLLING OF A NETWORK ADAPTER
Embodiments herein describe a host that polls a network adapter to receive data from a network. That is, the host/CPU/application thread polls the network adapter (e.g., the network card, NIC, or SmartNIC) to determine whether a packet has been received. If so, the host informs the network adapter to store the packet (or a portion of the packet) in a CPU register. If the requested data has not yet been received by the network adapter from the network, the network adapter can delay the responding to the request to provide extra time for the adapter to receive the data from the network.
SYSTEM AND METHOD FOR MANAGING INPUT-OUTPUT TIMEOUTS BASED ON DATA LOCATION
Methods and system for managing data in a distributed system are disclosed. To manage data in the distributed system, a host system may initiate an input-output (IO) transaction based on an occurrence of an IO transaction event being identified. The IO transaction may include storage commands to manage the data stored in a destination and/or to store the data in the destination. The IO transaction may have a dynamic timeout that defines a duration of time to receive confirmation of the IO transaction being processed by the destination prior to performing remedial processes by the host system.
