I am designing downlink smart antenna system using one TMS3206713B. In
my design the DSP has to be connected to 16 number of Digital to
analog converter (DAC), the output of these DAC must be sent to IF or
RF chain which then to be transmitted by the antenna elements
simultaneously.
My question is Can I use McBSP (EPI) to send the information to all
DAC serially, or I have to use GIOP (HPI)?
If I use McBSP, how can I separate and differentiate each channel
data for each DAC. If I am not mistaken in each frame transmission we
have only one transmit interrupt, and one frame synchronization signal
to control data transmission. In multi channel configuration it can be
programmed up to 128 channel which transmitted trough 8 time slot,
each time slot 16 channel.
My point is how can I separate and schedule the channel in
daughterboard? and how each channel can be differentiated from others?
Thanks a million for your highly valuable time.
