the most logical solution. However, when heavy data This paper describes the development of the tip-tilt mirror processing is needed, some doubts arise about the FPGAs control for an adaptive optics system based on the use of capabilities. Our experience is that for applications such as FPGA technology instead of using the traditional approach adaptive optics, where a lot of parallel processing is needed, with DSP or microprocessor. the use of FPGAs becomes a very attractive alternative,The aim of this work is to show that for this kind of capable of carrying out all the processing and even application the FPGA technology is not only a viable outperforming the DSP behavior when the amount of data solution but probably also the best one in some situations, increases in an important way. The FPGAs allow us to especially when a huge amount of parallel data processing reach the best trade-off for a particular application between is needed. This will probably be the case of adaptive optics more parallel processing and chip area, i.e., we can increase systemsfor verylarge telescopes (1).the level of parallelism at the expense of more FPGA A brief description of the whole adaptive optics system resources.will be given although the paper will focus especially on the One of the drawbacks argued by some people against tip-tilt mirror control and its implementation with FPGAs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
