Abstract: In examples, a device comprises control logic configured to detect an idle cycle, an operand generator configured to provide a synthetic operand responsive to the detection of the idle cycle, and a computational circuit. The computational circuit is configured to, during the idle cycle, perform a first computation on the synthetic operand. The computational circuit is configured to, during an active cycle, perform a second computation on an architectural operand.

Abstract: A soft-error resistant redundant latch including a first stage and second stage, each stage coupled to receive and to latch a binary signal in a latched state. Each stage is arranged to maintain the latched state at an intermediary node of the stage in response to a feedback path internal to the stage and in response to a stage output signal from the other stage. Each stage is arranged to generate a stage output signal in response to the latched state of the stage. The state of each stage is set to a first selected state by selectively coupling a stage set transistor between a first power rail and the intermediary node of the first stage in response to a set signal. The stage set transistor of the first stage and the stage set transistor of the second stage are complementary types.

Abstract: A multi-bit interlace latch includes a first and second latch that each have redundant active feedback paths to reduce the incidence of soft-errors. The first and second latches have active circuitry that includes nodes that are susceptible to radiation-induced soft errors. Active circuitry from the second latch is interlaced between active circuitry of the first latch to increase the isolation between critical nodes of the first latch. While the second latch circuit increases isolation between critical nodes of the first latch, the first latch may also benefit the second latch by increasing the isolation between critical nodes of the first latch as well.

Abstract: Reducing electromagnetic radiation from semiconductor devices. At least some of the illustrative embodiments are methods comprising driving a Boolean state to a signal pad of a semiconductor device (the driving through a transistor with a first drain-to-source impedance during the driving), and maintaining the Boolean state applied to the signal pad through the transistor with a second drain-to-source impedance, higher than the first drain-to-source impedance.

Abstract: In response to a selected analog applied to the input terminal of an analog-to-digital converter, the digitized output signal is stored in a buffer/register. In making a comparison with a predetermined value, a second buffer/register stores either a preselected value or a second digitized signal. A comparator is coupled to the first and the second buffer/register to provide the result of a comparison. In this manner, the central processing unit is not involved in the comparison testing procedure.
