  • Algebraic properties of multiple-valued modulo systems and their applications to current-mode CMOS circuits

    Publication Year: 1998, Page(s):364 - 368

    The paper presents the concepts of pseudoprime and modulo correlativity and establishes the relationships among completeness of modulo operations, uniqueness of solution of equations, invertibility of a square matrix, and correlativity of vectors in multiple-valued modulo system. It is shown that current-mode CMOS circuits are easy to design and economical using bounded operations View full abstract»

  • Method for minimising the switching activity of two-level logic circuits

    Publication Year: 1998, Page(s):357 - 363

    A new approach for implementing two-level logic circuits, which exhibit minimal power dissipation, is introduced. Switching activity reduction of the logic network nodes is achieved by inserting additional input signals in specific gates. Based on the statistical properties (i.e. static and transition probabilities) of the primary inputs, a new concept for grouping the input variables with similar... View full abstract»

  • Logical manipulations and design of tributary networks in the arithmetic spectral domain

    Publication Year: 1998, Page(s):347 - 356
    Cited by:  Papers (1)

    Formulae to represent composite arithmetic spectra of switching functions for basic logic connectives of such functions are shown. In contrast to the Walsh spectral domain, no complex dyadic convolution is involved in the calculation of composite arithmetic spectra, and the reintroduction of the transformation matrix has been avoided in the final formulae. Other important operations used in classi... View full abstract»

  • Memory alignment issues in real-time systems

    Publication Year: 1998, Page(s):341 - 346

    Real-time systems are proliferating, with applications in aircraft, spacecraft, chemical and power plants, and potentially in automobile-control systems. An important issue in such systems is aligning the memories of the processors after a transient failure. The authors show how the need to do this impacts system reliability, and should influence the amount of redundancy used as well as the task a... View full abstract»

  • Stack operations folding in Java processors

    Publication Year: 1998, Page(s):333 - 340

    Traditionally, the performance of a stack machine has been limited by the true data dependency. A performance enhancement mechanism, stack operations folding, was used in Sun Microelectronics' picoJava-I design, and it can fold up to 60% of all stack operations. The authors use the Java bytecode language as the target machine language, and study Java instruction folding on a proposed folding model... View full abstract»

  • Cylindrical architectures for 1-D recursive digital filters: A state space approach

    Publication Year: 1998, Page(s):327 - 332
    Cited by:  Papers (2)

    The paper considers the array processors' implementation of finite impulse response digital filters that require recursive computations. The state space representation is used to obtain efficient implementation via dynamically switchable systolic arrays (cylindrical type) of 1-D direct realisation. This direct description leads to a reduction in the computation speed and the throughput rate. Two s... View full abstract»

  • Generalised inverses in public key cryptosystem design

    The theory of generalised inverses of matrices over finite fields is highlighted potential tool in cryptographic research, by proposing a public key cryptosystem. Properties of the public key cryptosystem are analysed and compared with those of a previous public key cryptosystem. The idea is similar to the previous cryptosystem in terms of the usage of an error correction process. However, by usin... View full abstract»
