This paper describes a tightly integrated phased-array radar platform for a UAV-based sense and avoid application. The system leverages heterogeneous computing on a Zynq 7000 SoC processor to efficiently process the large streams of radar data required to guide a small Unmanned Air Vehicle (UAV) away from obstacles and intruding air vehicles. The system is mounted on a small UAV which requires stringent...
In the context of developing a compiler for a Alpha, a functional data-parallel language based on systems of affine recurrence equations (SAREs), we address the problem of transforming scheduled single-assignment code to multiple assignment code. We show how the polyhedral model allows us to statically compute the lifetimes of program variables, and thus enables us to derive necessary and sufficient...
Automatic parallelization in the polyhedral model is based on affine transformations from an original computation domain (iteration space) to a target space-time domain, often with a different transformation for each variable. Code generation is an often ignored step in this process that has a significant impact on the quality of the final code. It involves making a trade-off between code size and...
