#187995 - Bigger chips
Responding to: Jim Granville's previous message
Not that I didn't mean all ARM chips as bigger chips. But bigger ARM chips - like ARM9, ARM11 etc. Chips with normally external flash and RAM and intended to give 486, Pentium etc performance to embedded equipment. When designing a router with 100Mbit/s or Gbit/s network interfaces, it doesn't matter much if the processor needs an extra supply voltage.

The nice thing here is that since they were able to split the sizes of the I/O cells in relation to the geometry of the processor core, the cores are normally consuming so little power that it is rather easy to integrate DC/DC converters to keep the cores powered. So be it 8051 or ARM chips, we still get lots and lots of MIPS available at a very battery-friendly power consumption.
