hi i'm beginner in dsp and work in project that simulate the UMTS channel.
and need to connect dsp(6201) to fpga(spartan 3) via EMIF
and dsp to dsp via SPI (mcbsp)
now my needed help is that is there any one that do this later
please me important notes or probable problem in future.
thanks d...@yahoo.com

Dorsil,
I can add only two things.
1) the FPGA must be programmed to interface with EMIF.
2) the SPI bus works quite well. Just remember that one DSP must be configured as Master on the SPI
bus and the other DSP must be configured as Slave on the SPI bus.
Otherwise there will be conflicts with clocks, etc.

Hi dorsil,
What you should know is that I think that two DSPs can't connect by SPI port, because this method requires that one of the boards works as MASTER and the other as SLAVE, and I am quite sure that a DSP can't take the SLAVE role. I have communicated two DSP (6713) using EXTERNAL PERIPHERAL INTERFACE PORT, connecting CLKX0, FSX0, DX0 and GND of one DSP, to the CLKR0, FSR0, DR0 and GND of the other DSP. It works nice.
Keep on asking about SPI communication, because I am not sure at all.

Interfacing an FPGA to a C6000 series device EMIF is similar to interfacing a FIFO or
SRAMs. Here are some TI app notes that you can use for reference:
http://focus.ti.com/lit/an/spra543/spra543.pdf (EMIF to FIFO)
http://focus.ti.com/lit/an/spra542a/spra542a.pdf (EMIF to SRAM)
And this looks like a good one, "Interfacing Xilinx FPGAs to TI DSP Platforms Using
the EMIF":
http://www.xilinx.com/bvdocs/appnotes/xapp753.pdf
Xilinx wants to make it easy to use their FPGAs with TI DSPs, so that one should be
helpful.
