A non-volatile memory system comprises a memory structure and a control circuit connected to the memory structure.

A first end of the transistor is coupled to the control terminal, a second end of the transistor is coupled to a first end of the resistor, a control end of the transistor is coupled to a reference voltage, and a second end of the resistor is coupled to an input end of the logic circuit. The output terminal is coupled to an output end of the logic circuit.

Based on a Modified Gram-Schmidt (MGS) algorithm, QR decomposition techniques are optimized for parallel structures that provide arithmetic-logic unit (ALU) to ALU connectivity. The techniques utilize a different loop organization, but the dependent functional sequences of the algorithm are unchanged, thereby reducing likelihood of affecting error analysis and/or numerical stability. Some integrated circuit devices (e.g., FPGA) may implement hard floating-point (HFP) circuitry, such as a digital signal processing (DSP) block, distributed memories, and/or flexible internal connectivity, which can support the discussed high performance matrix arithmetic.

An integrated circuit may include a reconfigurable functional circuit block coupled to a microcontroller. The microcontroller may monitor a trigger register that receives trigger signals at a reconfiguration portion. The trigger signals may initiate corresponding reconfiguration operations by triggering the execution of instructions in a reconfiguration sequence program to load appropriate configuration data to configuration registers. The configuration registers may determine the operating mode of the functional circuit block by activating a subcomponent module in the functional circuit block. By providing a reconfiguration port that has full control of the reconfiguration of the functional circuit block, sensitive information regarding the implementation of the functional circuit block, the microcontroller, and connections therebetween may be protected while simplifying the design process for a custom logic circuit generated based on the reconfigurable functional circuit block.

An integrated circuit (IC) includes a first functional circuit block coupled to receive a supply voltage from a first supply voltage node. The IC further includes an input circuit and an output circuit. Responsive to receiving an input signal, the input circuit asserts an activation signal to cause one of a second supply voltage node and a third supply voltage node to be electrically coupled to the first supply voltage node. Subsequently the input circuit asserts a deactivation signal to cause the other one of the second and third supply voltage nodes to be electrically decoupled from the first supply voltage node. The output circuit is coupled to receive the activation signal and the deactivation signal, and configured to assert a first output signal subsequent to receiving the activation signal.
