hi friends
I'm building a project in which there are 4 channel RS422 data,20 DIPS
and one audio channel data coming continously.i.e. I have two seperate
mux/dmux unit.
1 unit mux unit is connected to dmux of other side & vice versa.Both
unit seperated by distance sends data continuously.
RS422= 1920bytes/sec/channel
DIPS= 800bytes/sec
Audio= 8Kbytes/sec
Total frame size is 64 bits excluding HDLC frame tags.We are using
HDLC protocol for framing and error detection.How i mux & dmux data at
a same time so that data can not be missed(bandwidth?).I am using TDM
multiplexing.
Audio signal is uses for telephonic conversetion.Can i implement
mux/dmux in single FPGA or two FPGA(because data is full duplex..
continuous)
Please give me some idea how to multiplex all these data
