C64x.. Overhead issue

Started by goelhss June 4, 2003
Hi All,
I am using C64x processor.
I am having 32-bit SDRAM and 16-bit FIFO as external memories which
are connected to DSP through EMIF.
As C64x DSP has 64-bit EMIF bus width, I have connected pins D0-D31
to 32-bit data bus of SDRAM and pins D32-D47 to 16-bit data bus of
FIFO.
Will there be any processing overhead in case of FIFO access with D32-
D47 connected to FIFO rather than connecting D0-D15 to FIFO? Regards,

Vishal
