A High Level, Algorithmic Programming Language and Compiler for Reconfigurable Systems

摘要

This paper presents a high level, machine independent, algorithmic, single-assignment programming language SA-C and its optimizing compiler targeting recon-figurable systems, and intended for Image Processing applications. Language features are introduced and discussed. The intermediate forms DDCF and DFG, used in the optimization and code-generation phases are described. Conventional and reconfigurable system specific optimizations are briefly introduced. The code generation process, using an abstract target machine, is described. Finally the performance effects of combinations of various optimizations are compared to hand coded C, using an edge detection algorithm followed by a threshold operator. Timing results are encouraging. Improvements of the compilation and code generation route are discussed.
