Test Generation and Design-for-Testability Based on Acyclic Structure with Hold Registers

We present a method of test generation for acyclic sequential circuits with hold registers. A complete (100% fault efficiency) test sequence for an acyclic sequential circuit can be obtained by applying a combinational test generator to all the maximal time-expansion models (TEMs) of the circuit. We propose a class of acyclic sequential circuits for which the number of maximal TEMs is one, i.e, the maximum TEM exists. For a circuit in the class, test generation can be performed by using only the maximum TEM. The proposed class of sequential circuits with the maximum TEM properly includes several known classes of acyclic sequential circuits such as balanced structures and acyclic sequential circuits without hold registers for which test generation can be also performed by using a combinational test generator. Therefore, in general, the hardware overhead for partial scan based on the proposed structure is smaller than that based on balanced or acyclic sequential structure without hold registers.

Health Information Systems and Registers

Health information systems are the basis of eHealth at regional and national levels. They provide the maintenance of traditional medical documents in out-patient clinics and hospitals in electronic form. At the same time, specialized registries are monitoring systems for the health status of people with certain diseases. However, the creation of registers as independent information systems, which takes place to this day, is now inadvisable, since the necessary information can be obtained from the Electronic Healthcare Record/ Electronic Medical Record. In this case, specialized registers are implemented as virtual systems of a temporary or permanent type. Regarding patient registers, they integrate data from electronic medical records and information from patients or their relatives.

A Morphological Compounding Analysis of Hausa Registers Use in Nigerian Cell-phone Market

This study aims to find the compound registers that are used among the Farm-Centre cell-phone marketers,analyse their compounding morphological structures,and explain the meaning they convey.The Farm-Centre Cell-phone Market is located in Kano metropolis,the largest city of Northern Nigeria.The study employs an ethnographic method of data collection and adopts Abubakar(2000)as a model of approach when analysing the structures of the compound registers.It is found that the registers have the following six morphological compound structures:(i)Genitive-based compounds[LG+N]N,(ii)Noun-based compounds[N+GL+N]N,(iii)Adjective-based compounds[Adj+N]N,(iv)Diminutive-based compounds[Dim+N]N,(v)Particle dà‘with’compounds[dà+N]N,(vi)Verb-based compounds[V+VN/Prep]V.Moreover,the registers are so special among the marketers because they convey meanings that are irrelevant to the conventional meanings known by the general speakers of the Hausa language.

Stability of Nonlinear Feedback Shift Registers with Periodic Input

The stability of Non-Linear Feedback Shift Registers(NFSRs)plays an important role in the cryptographic security.Due to the complexity of nonlinear systems and the lack of efficient algebraic tools,the theorems related to the stability of NFSRs are still not well-developed.In this paper,we view the NFSR with periodic inputs as a Boolean control network.Based on the mathematical tool of semi-tensor product(STP),the Boolean network can be mapped into an algebraic form.Through these basic theories,we analyze the state space of non-autonomous NFSRs,and discuss the stability of an NFSR with periodic inputs of limited length or unlimited length.The simulation results are provided to prove the efficiency of the model.Based on these works,we can provide a method to analyze the stability of the NFSR with periodic input,including limited length and unlimited length.By this,we can efficiently reduce the computational complexity,and its efficiency is demonstrated by applying the theorem in simulations dealing with the stability of a non-autonomous NFSR.

On observability of Galois nonlinear feedback shift registers over finite fields

Observability ensures that any two distinct initial states can be uniquely determined by their outputs,so the stream ciphers can avoid unobservable nonlinear feedback shift registers(NFSRs)to prevent the occurrence of equivalent keys.This paper discusses the observability of Galois NFSRs over finite fields.Galois NFSRs are treated as logical networks using the semi-tensor product.The vector form of the state transition matrix is introduced,by which a necessary and sufficient condition is proposed,as well as an algorithm for determining the observability of general Galois NFSRs.Moreover,a new observability matrix is defined,which can derive a matrix method with lower computation complexity.Furthermore,the observability of two special types of Galois NFSRs,a full-length Galois NFSR and a nonsingular Galois NFSR,is investigated.Two methods are proposed to determine the observability of these two special types of NFSRs,and some numerical examples are provided to support these results.

An Improved Power Efficient Clock Pulsed D Flip-flop Using Transmission Gate

Recent digital applications will require highly efficient and high-speed gadgets and it is related to the minimum delay and power consumption.The proposed work deals with a low-power clock pulsed data flip-flop(D flip-flop)using a transmission gate.To accomplish a power-efficient pulsed D flip-flop,clock gating is proposed.The gated clock reduces the unnecessary switching of the transistors in the circuit and thus reduces the dynamic power consumption.The clock gating approach is employed by using an AND gate to disrupt the clock input to the circuit as per the control signal called Enable.Due to this process,the clock gets turned off to reduce power consumption when there is no change in the output.The proposed transmission gate-based pulsed D flip-flop’s performance with clock gating and without clock gating circuit is analyzed.The proposed pulsed D flip-flop power consumption is 1.586μw less than the without clock gated flip-flop.Also,the authors have designed a 3-bit serial-in and parallel-out shift register using the proposed D flip-flop and analyzed the performance.Tanner Electronic Design Automation tool is used to simulate all the circuits with 45 nm technology.

Ethernet Controller SoC Design and Its Low-Power DFT Considerations

In this paper, an Ethernet controller SoC solution and its low power design for testability （DFT） for information appliances are presented. On a single chip, an enhanced one-cycle 8-bit micro controller unit （MCU）, media access control （MAC） circuit and embedded memories such as static random access memory （SRAM）, read only memory （ROM） and flash are all integrated together. In order to achieve high fault coverage, at the same time with low test power, different DFT techniques are adopted for different circuits： the scan circuit that reduces switching activity is implemented for digital logic circuits; BIST-based method is employed for the on-chip SRAM and ROM. According to the fault-modeling of embedded flash, we resort to a March-like method for flash built in self test （BIST）. By all means above, the result shows that the fault coverage may reach 97%, and the SoC chip is implemented successfully by using 0.25 μm two-poly four-metal mixed signal complementary metal oxide semiconductor （CMOS） technology, the die area is 4.8×4.6 mm^2. Test results show that the maximum throughput of Ethemet packets may reach 7Mb·s^1.

An Analysis of the Variation of Euphemism Under Register Theory

The euphemism is a phenomenon of language variation with different language varieties. And this phenomenon is closely related with social context. Register, as a concrete representation of context, especially its tenor of discourse, makes great influence on what kind of euphemism and what level of euphemism people will use to achieve effective communication. Therefore, euphemism as language variation will be analyzed from the perspective of tenor of discourse in Halliday's Register Theory in order to enhance learners' pragmatic awareness and pragmatic competence when learning English euphemism or in daily communication.
