This paper describes how a modular machine description, which specifies the functionality and the binary representation of an instruction set, can be transformed into a hardware model. This model is built from few generic hardware entities (registers, memories, arithmetic/logic operators, selectors and connections) and may eventually serve as an input to high-level hardware synthesis tools. The...

In this paper, we present a formal analysis of the constraints of the scheduling problem, and evaluate the structure of the scheduling polytope described by those constraints. Polyhedral theory and duality theory are used to demonstrate that e cient solutions of the scheduling problem can be expected from a carefully formulated integer linear program (ILP). Furthermore, we present an algorithm ...

It has been pointed out that a head-high pitch accent pattern (hereafter HLL) of a loanword in Japanese tends to be flattened and pronounced as a high level pitchaccent pattern (phonetically represented here as HHH) by younger generation. This paper attempts to clarify how Japanese who are in their twenties distinguish a high level pitch-accent pattern from a level pitch-accent pattern (hereaft...

The Semi-Automatic Digital Designer (SADD) is an experimental interactive knowledge-based design s stem, II whose domain of expertise is digital e ectronics. First, I want The SADD project has two goals. to provide an intermediate digital design problem solver for which a human expert can interactively provide the high-level functional descriptions-of-a circuit and which can take . high-level c...

Naturalness in human speech is dependent on a number of factors and the extent to which a text-to-speech synthesis system can account for these factors in its model will be a measure of its success in the marketplace. As well as the obvious factors of rhythm and intonation there is the more difficult question of modelling the variability in human speech. This paper discusses how SPRUCE [1], a h...

High-level synthesis tools from AutoESL made it possible to build a complex receiver for broadband wireless systems in a Xilinx Virtex-5 device. On Jan. 31, Xilinx announced it had acquired AutoESL. As such, you'll be hearing more about this exciting new technology in future issues of Xcell Journal.

| In this paper, a proole driven approach to behavioral synthesis is presented. For a given design and a set of input vectors, the switching activity in the design yields a measure of the power consumption. Every module in a parameterized module library is characterized by its average switching activity per input vector. For a given behavioral speciication, simulation using user-speciied inputs...

Scan paths are commonly used in digital design to improve the testability of sequential circuits since a full scan path provides complete controllability and observability for every bistable element. A traditional scan path is implemented after the circuit has been designed, with little regard to the actual circuit function. High-level synthesis can exploit knowledge of the circuit function to ...

Speech synthesis techniques have already reached a high level of naturalness. However, they are often evaluated on text reading tasks. New applications will request for conversational speech instead and disfluencies are crucial in such a style. The present paper presents a system to predict filled pauses and synthesise them. Objective results show that they can be inserted with 96% precision an...

Facial expression plays an important role in face to face communication in that it conveys nonverbal information and emotional intent beyond speech. In this paper, an approach for facial expression synthesis with an expressive Chinese talking avatar is proposed, where a layered parametric framework is designed to synthesize intermediate facial expressions using PAD emotional parameters [5], whi...
