(ay to dee converter) n. A hardware device that reads an analog signal—typically a voltage—compares it to a reference signal, and converts the resulting percentage to a digital value. Short for analog [..]

(like Cain's brother) abbr. A design language for creating the logic to be implemented in a simple programmable logic device. Short for Advanced Boolean Expression Language. Programs created with [..]

adj. Denotes a logic device or circuit where a logic 1 is a lower voltage than a logic 0.

n. A set of wires connected to a processor and all of the peripherals with which it communicates, for the purpose of selecting a specific memory location or register within a particular peripheral. If [..]

1. n. Allowing one memory location or register to be accessible at more than one address. Aliasing is a result of address decoding and often happens with peripheral control and status registers. For e [..]

adj. Describes data represented by a continuous range of values. The opposite of digital, in which all information is quantized. Analog is the way the world beyond the quantum level works. Part of the [..]

n. The element of a semiconductor device that accepts electrons. In a diode, for example, current passes from the anode to the cathode. On a diode, the anode is the terminal not marked by a band.

adj. Lacking periodicity; random. The term is most often used in the embedded context when scheduling periodictasks via RMA. The issue of what to do about aperiodic tasks and interrupts inevitably ari [..]

n. A task that responds to events of an application software

n. A piece of custom-designed hardware in a mass-produced chip. Abbreviated ASIC.
