No they haven't and they are not even close. OpenCL is a bad language for synthesis. The strength of an FPGA is deeply-pipeline-able sequential algorithms. C-based languages just aren't good at expressing/controlling pipelining, so the synthesizer/compiler has to infer this but that problem is too hard. You could change 1 line of code, a minor fixup and the clever optimizer fails and your design is suddenly 10x as big. |
