Abstract: Waveform circuitry and related apparatuses and methods are disclosed. An apparatus includes a memory device to store waveform data corresponding to a waveform, a processor, and a waveform circuitry to autonomously pre-process the waveform data independently from the processor and provide the pre-processed waveform data to one or more peripheral devices. A pre-processed waveform corresponding to the pre-processed waveform is data different from the waveform.

Abstract: Trap sub-portions of computer-readable instructions and related systems, methods, and devices are disclosed. A processing circuit includes a processing core including a program counter to cycle through addresses and a data storage device including computer-readable instructions stored thereon. Sub-portions of the computer-readable correspond to subroutines. Locations of the sub-portions within the data storage device are associated with the addresses. A first sub-portion at a first location within the data storage device is indicated by a first address. First trap sub-portions at first trap locations are indicated by first trap addresses. The first trap addresses are different from the first address by only a single bit. The first trap sub-portions instruct the processing core to execute first trap subroutines to jump to the first address or back to themselves.

Abstract: Autonomous memory access (AMA) controllers and related systems, methods, and devices are disclosed. An AMA controller includes waveform circuitry configured to autonomously retrieve waveform data stored in a memory device and pre-process the waveform data without intervention from a processor. The AMA controller is configured to provide the pre-processed waveform data to one or more peripheral devices.

Abstract: An electrical system includes an integrated circuit device including input/output (I/O) pins, a reset circuit, and an I/O circuit. The I/O circuit is operably coupled to the I/O pins. The I/O circuit is configured to selectively operate the I/O pins in an electrically floating state responsive to a system reset signal transmitted by the reset circuit. The I/O circuit is further configured to selectively operate the I/O pins in the electrically floating state responsive to a signal provided by a timer circuit independently from the reset circuit.

Abstract: An updated process parameter to an autonomous process control peripheral is autonomously obtained when made available by a process monitor peripheral, such as an analog-to-digital converter (ADC). The input can be obtained in response to a system event, such as a completed ADC conversion. The autonomous process control peripheral can compute an updated control variable each time the process variable is updated. When the updated control variable is calculated by the autonomous process control peripheral, the updated control variable is autonomously transferred or otherwise made available (e.g., through a register) by the autonomous process control peripheral to a process actuate peripheral. The process actuate peripheral uses the updated control variable to adjust the process being controlled.

Abstract: Disclosed systems, methods and devices relate, generally, to autonomous signal processing and autonomous signal processing units of a microcontroller. The autonomous data processing units may be configured to perform one or more functions independently, without input from a processing unit of the microcontroller, and may, monitor and/or perform operations that are part of one or more control loops that operate independent of the microcontroller processor. The control loops may or may not be in support of control loops monitored by the processor of the microcontroller.
