Abstract
The proposed architecture and related interfaces presents several advantages over the current design implementation practices. First, we provide a target independent view of the core datapath design and in particular execution control. The simple full/empty and pop/push set of signals protocol for retrieving/storing data from the channels allows for a smooth integration of behavioral design specifications with the structural descriptions that interface with memory. Second, given that the components of the proposed architecture and interfaces are parameterizable, we developed several code generation functions that can be integrated as part of a compilation system. Third, the decoupling of the scheduling of the computation in the code datapath with the memory accesses exposes several opportunities for memory operation optimizations, which are beyond the scope of current behavioral tools - memory operation pipelining and grouping[3]. The main disadvantage of the proposed approach is the incurred overhead of memory operations by the additions of an extra layer of abstractions (e.g., the stream channels) and their interfaces. While this is a potential disadvantage for increasing the latency of memory accesses, throughput and also clock rates can potentially be improved due to the simpler (and therefore possibly shorter) connections between the core datapath and the FIFO queues. Also, deeper conversion FIFO queues will allow overlapping of computation with communication. We believe the advantages of simpler interfaces and amenability for automation overall outweigh the disadvantages from additional latency. We have successfully integrated the external memory architecture presented here in the context of the DEFACTO[1] for a set of simple image processing kernels without a substantial performance sacrifice. © 2001 Non IEEE.

Abstract
We have briefly described a uniform estimation interface to two commercially available behavioral synthesis tools. Using this interface we have developed a simple design exploration strategy and applied it to a set of kernels computations. This experience reveals the importance of the proposed interface in allowing access to estimation features of existing tools to a wide range of users and programmers. © 2001 Non IEEE.

Abstract
An investigation on the application of fiber Bragg gratings for the interrogation of interferometric low-finesse Fabry-Perot cavities is reported. The proposed scheme is based on the generation of two quadrature phase-shifted signals that allows the recovering of the change in the cavity length. Besides being totally passive, this technique offers a high degree of flexibility and has the potential to be used in the interrogation of very short cavities.

Abstract
A theoretical and experimental investigation is reported on a novel all-fiber technique for interrogation of interferometric low-finesse Fabry-Perot cavities, It is based on the modulation of the spectral transfer function of a wavelength-division multiplexer, Results are given when both serrodyne and sinusoidal modulation formats are considered.

Abstract
The 5dpo team presented a solid set of innovative solutions. The overall workings of the team are presented. Mechanical and electronic solutions are explained and closed loop working is discussed. Main innovative features include I-R communications link and circular bar code for robot tracking. Low level control now presents a dynamics prediction layer for enhanced motion control. Team strategy is also new and a multi-layered high level reasoning system based on state charts allows for cooperative game play. © 2002 Springer-Verlag Berlin Heidelberg.
