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: 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.

The cured impregnation resin has a high strength, a high glass transition temperature and good adhesion properties, enabling a good durability and long-term stability of the reinforced structure.

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.

Abstract: Embodiments of the present disclosure provide systems and methods for realizing phase synchronization updates based on an input system reference signal SYSREF without the need to synchronously distribute the SYSREF signal on a high-speed domain. In particular, phase synchronization mechanisms of the present disclosure are based on keeping a first phase accumulator in the device clock domain and using a second phase accumulator in the final digital clock domain to asynchronously transmit phase updates to the final digital clock domain. Arrival of a new SYSREF pulse may be detected based on the counter value of the first phase accumulator, which value is asynchronously transferred and scaled to the second phase accumulator downstream. In this manner, even though the SYSREF signal itself is not synchronously transferred to the second phase accumulator, the phase updates from the SYSREF signal may be transferred downstream so that the final phase may be generated deterministically.
