| *** ARM Compiler *** | |
| -------------------- | |
| [..] RAM functions are defined using the toolchain options. | |
| Functions that are executed in RAM should reside in a separate | |
| source module. Using the 'Options for File' dialog you can simply change | |
| the 'Code / Const' area of a module to a memory space in physical RAM. | |
| Available memory areas are declared in the 'Target' tab of the | |
| Options for Target' dialog. | |
| *** ICCARM Compiler *** | |
| ----------------------- | |
| [..] RAM functions are defined using a specific toolchain keyword "__ramfunc". | |
| *** GNU Compiler *** | |
| -------------------- | |
| [..] RAM functions are defined using a specific toolchain attribute | |
| "__attribute__((section(".RamFunc")))". | |
