Placing code and constant data in ROM can lead to a big benefit in system cost. Since ROM area is typically one quarter the size of equivalent RAM the DSP silicon cost is lower. Performance is also improved since accessing ROM is faster than accessing external memory.

There are however software considerations when ROMing components. For example 'C6000 direct accesses to .bss global variab
