Custom instructions are one method and memory mapped accelerators are another. When the accelerator can operate quickly and contains few inputs custom instructions make sense to use. When there is a block of data to compute then a MM accelerator (sometimes with a DMA) makes more sense to use. One thing to keep in mind is that custom instructions block the processor pipeline.

So you have plenty of options but you should estimate computation times and input data sizes before choosing an accelerator method.
