“Dual_TX” (of the “TX” project). This task sends/receives control information and data
to/from the FPGA.
As described in paragraph 3.1.1, a Diamond DSP task (e.g. named “T6040_root.tsk”) can be
created by the SMT6040.
This task can be added to the MIMO_LTE Diamond project as explained in Chapter 3. This
new task can communicate, for example, with the “Dual_TX” DSP task. For this purpose, two
input and one output ports have to be added to the “Dual _TX” task.
Figure 26: SMT6040 diagram for MIMO_LTE demo.
These ports need to be connected to the input/output ports of the “T6040_root” task as
shown in Figure 27.
In the “main” function in “Dual_TX.c”, the functions “chan_out_message” and
“chan_in_message” can be used respectively to send data to “T6040_root” and to receive the
processed data from it. This is done during normal operation when the user selects option
number 6 of the MIMO_LTE menu.
Displays and “printf” statements (in the “main” function) will allow simple verification of the
behaviour of the “T6040_root” task designed in Simulink.
