Describing and Simulating Dynamic Reconfiguration in SystemC Exemplified by a Dedicated 3D Collision Detection Hardware

Abstract

<p>The ongoing trend towards development of parallel software and the increased flexibility of state-of-the-art programmable logic devices are currently converging in the field of reconfigurable hardware. On the other hand there is the traditional hardware market, with its increasingly short development cycles, which is mainly driven by high-level prototyping of products. To enable the design community to conveniently develop reconfigurable architectures in a short time-to-market, this thesis introduces the library ReChannel, which extends SystemC with advanced language constructs for high level reconfiguration modelling. It combines IP reuse and high-level modelling with reconfiguration. The proposed methodology was tested on a hierarchical FPGA-based 3D collision detection accelerator, is also presented. To enable implementation of such a complex algorithm in FPGA logic it had to be implemented using fixed-point arithmetic. Therefore a special method was derived that enables rounding of the used bounding-volumes without incurring the correctness of the non-intersection reports. This guarantees a correct overall result. A bound on the rounding error was derived that gives a measure of the number of false intersection reports, and thus on the run-time. A triangle and a quadrangle intersection test were implemented as the second</p>
