Difference: TexasInstrumentsTMS320 (r24 vs. r23)
DA255 is the TMS320 derivative used in the Creative Zen Touch and possibly other Creative / Dell DJ devices. The exact specifics of this variant (which is presumably a custom variant for Creative) are not fully known, but it is known that these are ARM processors with a C55x core. The entire tag on one chip reads "TMS320 DA255GHH? 4A-4AAFDEW". Unfortunately, Texas Instruments only gives the documentation out after signing a TI NDA.
