If we use i.MX 6Q, would there be much of a bottle neck when accessing<BR />memory configured as 32bit? We are trying to avoid the hassles that come with laying out a 64 bit bus, plus saving board space and BOM costs. Memory space is not an issue.</P><P><SPAN class="mce_paste_marker"></SPAN></P></BODY></HTML> Mon, 08 Jul 2013 21:54:32 GMT josephdobesh 2013-07-08T21:54:32Z 32 vs 64 bit bus questions https://community.nxp.com/t5/i-MX-Processors/32-vs-64-bit-bus-questions/m-p/260488#M25940 <HTML><HEAD></HEAD><BODY><P> We are deciding whether to design with a 32 bit bus or go to 64.
