XIP perfomrance versus internal FLASH in LPC546xx

[Jetcitycowboy]

Do you know how the execution time of the XIP (execute in place) feature of SPIFI on the LPC546xx parts would compare to  internal flash and also to the MK22FN512 executing code from internal flash?

Hi Kenneth,

You can refer to the "SPIFI Performance" section in the following presentation for more information. It compares the effective throughput for different flash types and there is a table showing the coremark performance results for the different memory locations:
