heap allocation on segmented ram

[Fibo]

The ram on the STM32H7 is segmented into non-contiguous sections. How would one be able to dynamically allocate memory in different sections of RAM? eg: put large objects in AXI-SRAM and small object that need fast access on DTCM.

I'm wondering if this is possible without a custom allocator however, links to open-source custom allocators or ideas for writing simple allocator would be appreciated.

My lazy approach in Keil was to stuff the additional regions into the the allocators linked-list.

Realistically you probably need different pools

Interesting, I also think that different pools are necessary since I would like to explicitly select the pool with which I am working. The "LwMEM" library mentioned by @Piranha​  has the features I'm looking for. Not sure about the reliability since it is under active development. It does have a few unit tests and decent documentation so that is a good start.

Code on master branch or under releases is usually passing the tests. Of course it doesn't mean it is bug free :)

I welcome you to contribute if you believe you need more features.
