Embedded System Glossary – T

Embedded System Terminology - T

Target - The embedded system platform, connected to the host, being developed.
Task - See Process.
Thermistor - A resistor with a resistance changes on-the-fly depending on the temperature the thermistor is exposed to. A thermistor’s resistor typically decreases as temperature increases.
Thermocouple - An electronic circuit that relays temperature differences via current flowing through two wires joined at either end. Each wire is made of different materials with one junction of the connected wires at the stable lower temperature, while the other junction is connected at the temperature to measured.
Thread - A sequential execution stream within a task. Threads are created within the context of a task, meaning a thread is bound to a task. Depending on the OS, a task can also own one or more threads. Unlike tasks, threads of a task share the same resources, such as working directories, files, I/O devices, global data, address space, and program code.
Throughput - The amount of work completed in a given period of time.
Timer - A peripheral that measures elapsed time, typically by counting processor cycles or clocks.
Tolerance - Represents at any one time how much more or less precise the parameters of an electrical component are at any given time based on its actual labeled parameter value. The actual values should not exceed plus (+) or minus (–) the labeled tolerance.
Tracepoint - Like a breakpoint except that, rather than stopping the program, a counter is incremented. Tracepoints are not supported by all debugging tools.
Transceiver - A physical device which receives and transmits data bits over a networking transmission medium.
Transducer - An electrical device that transforms one type of energy into another type of energy.
Transformer - A type of inductor that can increase or decrease the voltage of an AC signal.
Transistor - Some combination of P-type and N-type semiconductor material, typically with three terminals connecting to one type of each material. Depending on the type of transistor, they can be used for a variety of purposes, such as current amplifiers (amplification), in oscillators (oscillation), in high-speed integrated circuits, and/or in switching circuits (DIP switches and push buttons commonly found on off-the-shelf reference boards).
Translation Lookaside Buffer (TLB) - A portion of cache used by an MMU for allocating buffers that store address translations.
Trap - Software and internal hardware interrupts that are raised by some internal event to the master processor .
Truth Table - A table that outlines the possible input (s) of a logic circuit or boolean equation, and the relative output (s) to the input (s).
Twisted Pair - A pair of tightly interwrapped wires used for digital and analog data transmission.
