Embodiment Construction
[0020] A current preferred embodiment of the present invention is given and described in detail according to the accompanying drawings, so as to better understand the functions and features of the present invention.
[0021] like figure 1 As shown, the channelized STM-1 access distribution system of the present invention includes an access unit, a multi-core processing core unit and a switch output unit.
[0022] like figure 2 As shown, the access unit includes a plurality of channelized STM-1 photoelectric signal conversion modules, an FPGA (Field-programmable Gate Array, programmable logic gate array) chip with a built-in memory controller, and a user controlled by the memory controller Memory for caching intermediate data. The built-in memory controller of the FPGA chip can be a DDRII (Double Data Rate 2, double data transfer rate second-generation solution) memory controller, and the memory controlled by it can be a 128Mb DDRII (model such as EM58128) memory. Each STM-...
