Dear everyone:
In the FPGA code of halfband_decim,v of USRP1, it has a input strobe_in,
which indates a new data comes. Strobe_in is determined by the decimation rate.
For example if we decimate by 6 we write to the register FR_DECIM_RATE 6/2-1=2
and strobe_in comes high every 3 clocks.
My question is that if I want to use halfband filter only to get a
decimation of 2 (for other purpose of my FPGA project, not used in USRP), how
should I set strobe_in? I noticed that whether I set it equal to the clock or
set it equal to 1, the strobe_out always comes high every two clocks and
data_out is different. So can you tell me how I should set strobe_in? Besides
my data are 8 bits wide, is it proper to pad 0 to my data to reach 16 bits wide?
