CodeQuickAccess and DataQuickAccess

[1920844004]

#define AT_QUICKACCESS_SECTION_CODE(func) __attribute__((section("CodeQuickAccess"))) func

#define AT_QUICKACCESS_SECTION_DATA(func) __attribute__((section("DataQuickAccess"))) func

How do I use this "CodeQuickAccess" feature? Can it speed up code execution?

Hello zhihui liu,

Please check the following application note: Using the i.MX RT FlexRAM. The CodeQuickAccess section corresponds to the  I-TCM(Instruction-Tightly Coupled Memory) and the DataQuickAccess to the D-TCM(Data-Tightly Coupled Memory).

All TCM interfaces run at the same frequency as the Arm Cortex-M7core and are synchronous to each other.

Hope it helps!

Victor.
