A pragma based approach for mapping MATLAB applications on a coarse grained reconfigurable architecture

This paper describes a tool that maps DSP functions written in MATLAB on a coarse grained reconfigurable platform with the help of pragmas. Pragmas are architectural hint directives that constraints the design implementation in terms of allocation/binding and explore specific features of platform. The pragmas are symbolic and parametric to make DSP functions generic in terms of the dimension. By sweeping these parameters, the tool can generate solutions of different dimension and varying degrees of parallelism from the same algorithmic level code. The tool performs scheduling, synchronization, control and interconnect generation for each such solution. This enables the pragma annotated functions to serve as generic library elements in a system level synthesis framework that sweeps through the parameters to select a function implementation of right size and optimal parallelism, thus enabling efficient system level design space exploration. In this paper, we describe these pragmas, their syntax, semantics and richly illustrate their usage with examples.
