The WORD on ARM's big.LITTLE Cortex-A15/A7 design philosophy from Jack Ganssle
November 8, 2011
I’ve written up many bits of wisdom from my friend Jack Ganssle before and his latest Embedded Muse newsletter carries a lead article on the new ARM big.LITTLE design philosophy that teams a high-powered ARM Cortex-A15 processor core with a much smaller but architecturally identical ARM Cortex-A7 processor core.
The reasoning behind the ARM big.LITTLE SoC design philosophy is to run the Cortex-A15 when there’s lots of work to do and to switch over to the Cortex-A7 core when there’s less work to do—thus saving power. Here’s what Jack wrote:
