This paper presents two architectures for 2-D discrete wavelet transform (DWT) and inverse DWT (IDWT). The first consists of transform module, RAM module and address sequencer. The transform module, which takes uniform and regular structure with local communication, offers many advantages, e.g. simple control flow, full hardware-utilization and low-power. The second architecture features parall...

1 The need for modules in the development of large programs is well known while meta-programming is widely regarded as a simple yet powerful methodology for knowledge representation and reasoning. Thus if we wish to reason about large knowledge bases, it is desirable that meta-programs should be designed to reason about modular programs. This paper describes a module system which allows the mod...

We present in this paper the preliminary design of a module system based on a notion of components such as they are found in COM. This module system is inspired from that of Standard ML, and features first-class instances of components, first-class interfaces, and interface-polymorphic functions, as well as allowing components to be both imported from the environment and exported to the environ...

Let V be a simple vertex operator algebra and let G be a finite automorphism group of V . In [DY], it was shown that any irreducible V -module is a completely reducible V module where V G is the G-invariant sub-vertex operator algebra of V . In this paper, we give an alternative proof of this fact using the theory of skew group algebras. We also extend this result to any irreducible g-twisted V...

In this paper, we discuss the role and utility of synthetic vision in computer games. We present an implementation of a synthetic vision module based on two viewports rendered in real-time, one representing static information and the other dynamic, with false colouring being used for object identification, depth information and mo vement representation. We demonstrate the utility of this synthe...

Fuzzy relations are simple mathematical structures that enable a very general representation of fuzzy knowledge, and fuzzy relational calculus offers a powerful machinery for approximate reasoning. However, one of the most relevant limitations of approximate reasoning is the efficiency bottleneck. In this paper, we present a module for fast fuzzy inference through relational composition, with t...

This paper presents TKDM, a PC-based high-performance reconfigurable computing environment. The TKDM hardware consists of an FPGA module that uses the DIMM (dual inline memory module) bus for high-bandwidth and low-latency communication with the host CPU. The system’s firmware is integrated with the Linux host operating system and offers functions for data communication and FPGA reconfiguration...

Innovative approaches to the design of a high-performance package module accommodating a 32× 32 array of surface-active devices indium bump bonded to a 8× 8 mm2 VLSI chip are presented. Electrical, thermal and optomechanical design considerations are discussed and experimental performance results of a prototype implementation are described. The package module supports 139 impedance-controlled s...

The simple 7-dimensional Malcev algebra M is isomorphic to the irreducible sl(2,C)-module V (6) with binary product [x, y] = α(x ∧ y) defined by the sl(2,C)-module morphism α : Λ2V (6)→ V (6). Combining this with the ternary product (x, y, z) = β(x∧y) ·z defined by the sl(2,C)-module morphism β : Λ2V (6)→ V (2) ≈ sl(2,C) gives M the structure of a generalized Lie triple system, or Lie-Yamaguti ...
