Using NOC technology to improve Photoelectric Encoder system for LAMOST spectroscopes
Large Sky Area Multi-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 Corporations Qsys tool. Besides, a comparison of system performance in different 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.
