This paper describes the compilation of high-level language programs written in a singleassignment language called SA-C into the binary codes used for programming recon gurable hardware. The primary application domain is image processing. The paper describes the SA-C language, the compiler and the optimizations it performs, the process of converting the intermediate form called data ow graphs i...

The frontal eye field (FEF), in the prefrontal cortex, participates in the transformation of visual signals into saccade motor commands and in eye-head gaze control. The FEF is thought to show eye-fixed visual codes in head-restrained monkeys, but it is not known how it transforms these inputs into spatial codes for head-unrestrained gaze commands. Here, we tested if the FEF influences desired ...

Most of the codes that have an algebraic decoding algorithm are derived from the Reed Solomon codes. They are obtained by taking equivalent codes, for example the generalized Reed Solomon codes, or by using the so-called subfield subcode method, which leads to Alternant codes and Goppa codes over the underlying prime field, or over some intermediate subfield. The main advantages of these constr...

An iterated refinement procedure for the Guruswami–Sudan list decoding algorithm for Generalised Reed–Solomon codes based on Alekhnovich’s module minimisation is proposed. The method is parametrisable and allows variants of the usual list decoding approach. In particular, finding the list of closest codewords within an intermediate radius can be performed with improved average-case complexity w...

This paper proposes an interchange mechanism for geographic data through the use of intermediate Web Services. We also present an auxiliar software that codes geographic Web Services according to the OpenGIS specifications. The main objective of this work is facilitate the creation, publication and consumption of geographic Web Services.

An automatic scaling C program translator is developed for the eecient execution of application programs in xed-point digital signal processors. The program for range estimation is automatically generated by inserting codes which collect the statistics of each signal during the simulation. With the range information, the number of shifts needed for the scaling is determined and the oating-point...

In this paper we model code selection by tree series transducers. We are given an intermediate representation of some compiler as well as a machine grammar with weights, which reflect the number of machine cycles of the instructions. The derivations of the machine grammar are machine codes. In general, a machine grammar is ambiguous and hence there might exist more than one derivation of an int...

This paper draws a parallel between document preparation and the traditional processes of compilation and link editing for computer programs. A block-based document model is described which allows for separate compilation of various portions of a document.These portions are brought together and merged by a linker program, called dlink, whose pilot implementation is based on ditroff and on its u...

Two simultaneous three wave mixing processes are analyzed, where an input frequency is converted to an output frequency via an intermediate stage. By employing simultaneous phase-matching and an adiabatic modulation of the nonlinear coupling strengths, the intermediate frequency is kept dark throughout the interaction while obtaining high conversion efficiency. This feat is accomplished in a ma...
