The current memory interface does its job for our use case of developing open source cores for cryptography. However we do not exactly support APB (almost there) and it could be nice to do it once and just stick to it for all cores. Also, in the future we can have support for both APB and AXI which is the preferred protocol for SOCs.
We wouldn't actually need to test both, since we already have one for the APB-like interface. But it's a feature that's interesting to do to learn about common protocols and for our library.
