#177544 - 8051 + MAC Responding to: ???'s previous message |
Christoph Franck said:
I wouldn't consider a '51 with added-on hardware filters a DSP - it lacks the flexibility of an actual DSP. Now, if you add a MAC unit, you'd get closer to a "real" DSP, but the '51 architecture still has severe limitations (memory, etc) that a true DSP wouldn't have. Actually there are already several 8051's with an integrated MAC. The problem is getting the data in and out of it fast enough, I guess. |
