TMS320C6678: 48 channel audio output scheme

Hello!

The problem looks twofold: on one side there should be enough data throughput, on another - enough connections. The latter is simpler, there is no easy scheme to connect 48 slave devices to C6678, thus some kind of glue logic, presumably FPGA, would be required.

Next, calculate raw throughput required as 96000 x 24 x 48 = 110 592 000 bps, over 100 Mbps of useful throughput, without overhead. That is well above I2C rate, EMIF16 not a candidate, so reminder is highspeed serial. One may try to link FPGA with DSP over PCie, then let FPGA demux those 48 channels and feed them to DACs.
