- Well, when speaking about 24 and 32 bits, it was about data and not
- address bits: the DSP56001 has a data path of 24 bits ! (and an internal
- register size of 56 bits hence the name. Little game: guess what's
- the register size of the DSP 96002 ?)
- This width difference surely poses some problems for implementing
- DMA or other memory accesses !
