Are you sure you didn't add an order of magnitude there? A quad-core, 3GHz processor has 12,000M core-cycles a second. I find it hard to believe that even modern processors dispatch 8 instructions per cycle in a single core. Mind you, your main point - that a 400MHz processor is a bit underpowered - is spot-on. My new cellphone, for example, has a two-core, 1GHz processor. That's about 5x what Paul quoted for the in-car entertainment system. But the car system also controls more important functions (keyless entry, for one), so it has to be significantly more robust than one used in a phone, where the worst that can happen would be a dropped call. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
