static void init_exceptions ( void  )

Initializes MCU exceptions.

init_heap ( void  )

Initializes the heap.

References __heap_end__, and __heap_start__.

static void init_hmatrix ( void  )

Initializes the HSB bus matrix.

Low-level initialization routine called during startup, before the main function.

int main ( void  )

Main function of the example memory manager.

This example shows how memory can be allocated from different memory spaces. The default allocation will get memory from the internal SRAM. By using the "memory space" functionality of the memory manager it is possible to use other memory spaces as resources like an attached SDRAM.
