Vector Pascal

Vector Pascal is a language designed to support elegant and efficient expression of algorithms using the SIMD model of computation. It imports into Pascal features derived from the functional languages APL and J, in particular the extension of all operators to work on vectors of data. The type system is extended to handle dimensional analysis. Code generation is via the ILCG system that allows ...

Vector Pascal, an array language

Vector Pascal is a language designed to support elegant and efficient expression of algorithms using the SIMD model of computation. It imports into Pascal abstraction mechanisms derived from functional languages having their origins in APL. In particular it extends all operators to work on vectors of data. The type system is extended to handle pixels and dimensional analysis. Code generation is...

Pascal Challenge: Linear Support Vector Machines

ξ(w; xi, yi) = max(1− yi(w xi), 0), We consider the LIBLINEAR package (available at http://www.csie.ntu.edu.tw/~cjlin/ liblinear), which can handle L1and L2-loss linear SVMs. The L1-SVM solver implemented in LIBLINEAR employes a coordinate descent method to solve the dual problem. Details are in [1]. This method is very useful for large sparse data with a huge number of instances and features. ...

Compiling for a Heterogeneous Vector Image Processor

We present a new compilation strategy, implemented at a small cost, to optimize image applications developed on top of a high level image processing library for an heterogeneous processor with a vector image processing accelerator. The library provides the semantics of the image computations. The pipelined structure of the accelerator allows to compute whole expressions with dozens of elementar...
