ONT传输会聚(TC)层上行组帧中基于IP核的ATM信元存储方案及其FPGA实现

Design of ATM Cell Memory Based on IP Core and It's FPGA Implementation in Upstream-framing of ONT TC Layer

IP核可重用设计方法是未来大规模集成电路的主流设计方法。本文论述了在设计光网络终端ONT传输会聚(TC)层上行组帧中,一种将IP核模块与VHDL语言描述相结合的ATM信元存储方案,并用FPGA予以实现,得出IP核设计方法的优越性。

Reusable design method of IP core is the main method in designing large scale integrated circuits.In this paper, a storage method of ATM cell is described using the combination of IP core module and VHDL language description in designing upstream-framing of ONT TC layer. The ATM cell memory is implemented with FPGA and the superiority of design method based on IP core is concluded.
