A process design kit (PDK) is a set of files used within the semiconductor industry to model a fabrication process for the design tools used to design an integrated circuit. The PDK is created by the foundry defining a certain technology variation for their processes.

In automata theory, a deterministic pushdown automaton (DPDA or DPA) is a variation of the pushdown automaton. ... A deterministic pushdown automaton has at most one legal transition for the same combination of input symbol, state, and top stack symbol. This is where it differs from the nondeterministic pushdown automaton.

TPTK. TPTK is the abbreviation for top pair/top kicker. In poker variants with community cards, it describes a pair made up from one player card and the highest community card where its side card or kicker is the highest kicker possible.

PDA is an automaton with finite states and the memory can be unbounded. With the application of a PDA, it will be able to recognize a CFG that looks like this: {0^n 1^n | n∈ ℕ}. A PDA can be different types of transitions, such as expansions, reductions, and conditional.

A PDK gearbox uses hydraulically actuated wet-clutch packs, one enveloped around the other. One clutch connects reverse, first, third, fifth and seventh gears, the other handles second, fourth and sixth. ... Blue highlights which gears the clutch operates. The internal gears and clutch pack of a PDK transmission.

The Data Pointer (DPTR) is the 8051's only user-accessible 16-bit (2-byte) register. The Accumulator, R0–R7 registers and B register are 1-byte value registers. DPTR is meant for pointing to data. It is used by the 8051 to access external memory using the address indicated by DPTR.

VHDL is not a software programming language, rather it describes hardware. Hardware fundamentally works in parallel (for example, two gates will perform their function on their inputs simultaneously), and hence concurrency is built into VHDL.

VLSI(Very Large Scale Integration) is the technology used to create small microchips which are capable of performing various operations e.g. Multiplexers, Encoders, flipflops. Many such functionalities are combined in ASICs(Application Specific Integrated Circuits).

PDH stands for Plesiochronous Digital Hierarchy and SDH stands for Synchronous Digital Hierarchy. Both PDH and SDH are terminologies associated with digital multiplexers used in exchanges. The different hierarchies having different bit rates are combined.

If you need to install the PDK, do the following: Go to https://pdk.cadence.com/home.do and login. If you do not already have an account, then register and create one. Once you are logged in, continue.

The JK flip flop is basically a gated SR flip-flop with the addition of a clock input circuitry that prevents the illegal or invalid output condition that can occur when both inputs S and R are equal to logic level “1”.

In VHDL, you can specify a variable or signal's initial value in its declaration. For example, the following VHDL fragment assigns an initial value of '1' to the signal enable: signal enable : std_logic := '1'; A VHDL variable or signal whose declaration includes an initial value has an explicit initial value.

Porsche Doppelkupplung (PDK) 7-speed PDK, featuring both a manual and an automatic mode, is available as an option and offers extremely fast gear changes with no interruption in the flow of power. Not to mention even faster acceleration performance and a reduction in fuel consumption over the manual transmission.

Definition: The DPSK stands for “Differential phase-shift keying”. It is one type of phase modulation used to transmit data by altering the carrier wave's phase. In this, the modulated signal's phase is moved e to the element of an earlier signal.

A VHDL description has two domains: a sequential domain and a concurrent domain. The sequential domain is represented by a process or subprogram that contains sequential statements. These statements are exe- cuted in the order in which they appear within the process or subprogram, as in programming languages.
