Abstract: The described embodiments include an electronic device having a processor. The processor performs operations for handling watermarks in files. As part of the operations, the processor processes a portion of a file in a classification neural network to determine whether a watermark is present in the portion of the file. Based on a result of the processing, the processor performs an update associated with the watermark in the portion of the file. The processor then provides the updated portion of the file.

Abstract: A system and method are presented for digital communication via a time division multiplexed serial data stream. A serial communication system according to the present invention includes a serial communication controller having a set of functional units each configured to perform a specific function of a serial communication protocol. The functional units are operably coupled in series in order to produce digital data according to the serial communication protocol. The set of functional units operates alternately upon an active one of the multiple serial data channels within the time division multiplexed serial data stream. Each functional unit may be a state machine including one or more programmable registers for storing state information which determines the operating state of the functional unit.

Abstract: A network interface unit is presented including a microcontroller having multiple blocks of programmable logic that are variably configurable to perform selected functions. The network interface unit may be configured to assemble, transmit, and receive data units (i.e., frames) of one communication protocol, then later reconfigured to assemble, transmit, and receive frames of another protocol. The microcontroller includes several components formed upon a single monolithic semiconductor substrate, among them an execution unit. The execution unit includes a processor core and multiple configurable logic blocks (CLBs) coupled to the processor core. The processor core is configured to execute instructions, for example x86 instructions. Each of the multiple CLBs includes programmable logic which may be, for example, PLA circuitry, PAL circuitry, or FPGA circuitry. The programmable logic includes programmable switching elements such as, for example, EPROM elements, EEPROM elements, or SRAM elements.
