Paper Abstract

This paper presents a spatially reconfigurable program module for FIR filter that can be used in FPGA design. Such a module is highly scalable and parameterized. In general, such program module describes classical probe lm size dependent arrays, fixed size arrays and arrays with increased performance. In the last case the problem is mapped into higher-dimensional array. As a theoretical basis we will use the theory of regular arrays. Efficient reconfiguring requires the rewriting of algorithms using algebraic transformations. For this purpose we will use the partitioning and specific pipe-structures. We will also use multi-dimensional time to increase the range of different array topologies. The description of a module includes pre scheduled designs, so, the reconfiguring does not require solving integer linear programming problems, and thus, can be used at run-time. The paper presents a family of scalable array structures for FIR filter: 1-D, 2-D and 3-D structures with different input/output positioning and performance.
