I'm trying to transfer data using FlexIO2
FlexIO2 and memory are connected by eDMA and FlexIO2 transfer data at 15Mbps using 16 data line and 1 clock line
I set SEMC clock to 150MHz
When I transfer 384Kbyte with internal SRAM, it takes about 14ms
But when I transfer 384Kbyte with external SDRAM, it takes about 36ms.
Is it the correct performance difference between internal SRAM and external SDRAM ?
Is there any way to improve performace with external SDRAM?
Hi YongJin Choi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1)Is it the correct performance difference between internal SRAM and external SDRAM?
-- The difference between the SRAM and SDRAM's performance is normal.
2) Is there any way to improve performance with external SDRAM?
Have a great day,
TIC
