eXecute In Place

With eXecute In Place (XIP), you can run the kernel directly from flash. Because you do away with the extra step of copying the kernel to RAM, your kernel boots faster. The downside is that your flash memory requirement increases because the kernel has to be stored uncompressed. Before deciding to go the XIP route, also be aware that the slower instruction fetch times from flash can impact runtime performance.
