Abstract
Large Sky Area Mu lti-Object Fiber Spectroscopic Telescope (LAMOST), consists of 16 spectroscopes which have lots of motors should be controlled. This paper mainly introduces how to use Network-on-chip (NOC) technology to improve the photoelectric encoder system of LAMOST spectrometer controller via Altera Corporation's Qsys tool. Besides, acomparison of system performance in dif ferent pipeline stages was made. The realization of overall design follows a hierarchical interconnection idea, which significantly improves system performance, decreases Logic Elements (LEs) usage, and shortens design period compared with the previous SOPC-based approach.
