John Syn, Wandboard Quad does have 64 bit memory bus. P.S. I don't know who needs dual DSP onboard because TI definitely will not support them as should like it was for omap3/dm37. I'd better have well supported hardware video encoder/decoder rather than double general purpose DSPs without any software support 09 Ноя 2014 г. 1:21 пользователь "John Syn" <john3...@gmail.com> написал:
