Abstract: A method for meeting quality of service (QoS) requirements in a flash controller that includes one or more instruction queues and a neural network engine. A configuration file for a QoS neural network is loaded into the neural network engine. A current command is received at the instruction queue(s). Feature values corresponding to commands in the instruction queue(s) are identified and are loaded into the neural network engine. A neural network operation of the QoS neural network is performed using as input the identified feature values to predict latency of the current command. The predicted latency is compared to a first latency threshold. When the predicted latency exceeds the first latency threshold one or more of the commands in the instruction queue(s) are modified. The commands are not modified when the predicted latency does not exceed the latency threshold. A next command in the instruction queue(s) is then performed.

Abstract: One or more examples relate to a detector. A signal that the detector is configured to sense is a differential value. Such a differential value may be indicative of a difference in self-capacitance indications that are exhibited at first and second internal capacitors. Such a differential value may be proportional to a relationship between a first material and a second material present at a device-under-test coupled to electrodes of the detector. Such a differential value may be proportional to a vertical elevation of a surface of a material present at a device-under-test coupled to electrodes of the detector. A difference in coupling capacitances may be obtained by performing complimentary acquisition processes utilizing symmetric capacitive sensors. When the acquisition processes are performed substantially simultaneously, coupling error indications that may be present in the self-capacitance indications are not present in the differential value.

Abstract: A method and apparatus for decoding in which a first failed decode operation is performed on raw bit values of a FEC block by a LDPC decoder. When the FEC block is determined to be a trapped block an updated LLR map is generated; the updated LLR map and either the raw bit values of the FEC block or a failed-decode-output-block from a previous failed decode operation on the trapped block are provided to the LDPC decoder; a decode operation of the LDPC decoder is performed using the updated LLR map on the bit values of the FEC block or the failed-decode-output-block from the previous failed decode operation; and the generating, the providing and the performing are repeated until the decode operation is successful or until a predetermined number of trapped-block-decoding iterations have been performed. When the decode operation is successful in decoding the FEC block the codeword is output.

Abstract: A method and apparatus in which a data stream generated by a previous network node, a cumulative phase offset report (CPOR) and a client rate report (CRR) are received. A counter accumulating a PHY-scaled stream clock (IPSCk) is sampled at a nominal sampling period (Tps) to obtain a cumulative PHY-scaled count (CPSC). A PHY-scaled stream phase offset (PSPO) is calculated that indicates phase difference between a PHY-scaled stream nominal bit count (LPSD) and an incoming PHY-scaled count delta (IPSD), where IPSD indicates CPSC increment between successive CPSC samples. The data stream is demultiplexed to obtain CBR carrier streams that include a previous network node CPOR (CPOR-P) and a previous network node CPO (CPO-P). A CPO is calculated that is a function of CPO-P and the PSPO. CPO-P is replaced with the calculated CPO. The CBR carrier streams are multiplexed into intermediate-network-node data streams that are transmitted from the intermediate-network-node.
