good morning Please I would a vhdl code for scrambler/descrambler which takes as parameter binary data and the scrambler polynomial generator with its intial sequence. Also I would a code for a double polynomial generator for example UMTS had two polynomial generator : P1 (X) = X^17 + X^7 + 1 P2 (X) = X^17 + X^10 + X^7 + X^5 + 1 it joined a scrambler/descrambler matlab code which polynomial generator is P (X) = 1 + X^5 + X^12 + X^16 Thx in advance
> please help me
Maybe someone will help you, if you start with VHDL coding and ask a
particular question about a specific problem. But this forum is not
intended to deliver your homework completely.
Have a look for some LFSR implementations in VHDL. There are plenty of
them on the web and even each FPGA supplier has a bunch of
implementations (see Xilinx xapp220, xapp217, xapp211, xapp210,
xapp052...)
