Star ARM Pushes Envelope with New Multicore Chips
Linked by Thom Holwerda on Fri 18th Sep 2009 17:30 UTC, submitted by Moulinneuf
Hardware, Embedded Systems We all know (and love?) ARM as the company which focusses on licensing designs for power-efficient yet still powerful processors, mostly used in embedded devices. The Cambridge company has been looking to expand into the netbook market, and has now announced a new step in this process with a number of new multicore Cortex-A9 designs.

There already is work underway to port Haiku to ARM so don't be surprised if there is something bootable in the next year or so.

Question: It is my understanding that BeOS/Haiku uses the 'HALT' instruction to lower power use when the CPU is idle and waiting for an interrupt, does the ARM have such an instruction/mode and if it does how much power is used compared to normal CPU needs?

I am thinking in term of a large number of cores when a number of them will sit idle when there is not a heavy load on the system.
