what do you mean by that "uses ASIC level special chip"?
ASICs are also used in a wide variety in cisco products since years,
e.g. PFC/Sup/6500/7600, GSRs, CRS etc..

ASRs uses the Quantum Flow Processor - maybe it also uses some asics
but the main focus lies in that platform on the software architecture
part. The problem many hardware architectures have is the flexibility
and "simplicity" of feature/software implementation which are often
just not possible in many hardware architectures or very hard to implement
and take years until working. The ASR has nearly the same features
as a VXR, which is ciscos swiss-army-knife in terms of features so its
a bit different then the other hardware products around...
