Abstract: Systems and methods for compensating a transmit signal for charge trapping effects of a power amplifier are provided. In certain embodiments, a non-linear filter is trained based on time aligning a first set of observations taken from digital transmit data prior to conversion to a radio frequency transmit signal, and a second set of observations taken from an output of a power amplifier that amplifies the radio frequency transmit signal. In certain implementations, the first set of observations and the second set of observations are obtained without decimation. Rather, decimation is provided after timing alignment. By implementing the DPD system in this manner, signal data is not lost by decimation and more accurate timing alignment between the sets of observations is achieved.

Abstract: Push-pull mechanisms for handling dataflow between circuit blocks are disclosed. In certain embodiments, a network of dataflow gaskets includes a source gasket coupled to a first circuit block and a destination gasket coupled to a second circuit block. The source gasket and the destination gasket are connected by a push mechanism that uses write channels to write data from the source gasket to the destination gasket, and a pull mechanism that uses read channels to read data from the source gasket to the destination gasket. The source gasket and the destination gasket can switch between a push mode and a pull mode to ease traffic based on data available to transfer at the source gasket and/or a space available to receive data in the destination gasket. For example, a transfer size register can be used to set a threshold to aid between the mode transitions.

Abstract: Apparatus and methods for facilitating data movement among circuit blocks are disclosed. In certain embodiments, dataflow gaskets with circular buffers are deployed in any number or arrangement to achieve efficient on-chip data movement among different circuit blocks of the die. Each dataflow gasket can be attached to a corresponding circuit block using tightly coupled memories to provide low latency and fast access to incoming and outgoing data streams. Furthermore, memory allocation and buffer management can be handled by the internal logic in the dataflow gasket to reduce or eliminate software development efforts. For example, the dataflow gasket can use circular buffers to allow the circuit block to access the dataflow gasket's memories without needing to understand the internal memory addressing of the dataflow gasket.

Abstract: In an embodiment, systems and methods for reviewing payments using artificial intelligence are provided. Training data is collected that includes payments made by insurance payors for claims received from medical providers. The payments may have been verified as correct and include metadata about the associated claim such as the medical service and whether the claim was in or out of network.

The predicted amount is compared with the actual payment amount and is used to determine if the payment is anomalous. If the payment is anomalous, it is provided to an auditor who checks the payment for compliance with a contract between the payor and the provider.

Abstract: Radio transceiver control interfaces are provided herein. In certain embodiments, a semiconductor die includes a group of transmitters and a group of receivers that operate as a transceiver. Additionally, a group of common pins are used to control settings of both the transmitters and receivers. In one example, data received on the common pins can be used to establish enable settings for each of the transmitters and receivers. Thus, rather than using a one-to-one correspondence between a pin and the setting of a particular transmitter or receiver, a mapping is used between the common pins and the settings of the transmitters and receivers.
