The Cortex A15 is based on the ARMv7A architecture and introduced the Large Physical Address Extensions (LPAE): http://www.arm.com/products/processors/cortex-a/cortex-a15.php http://www.arm.com/files/pdf/at-exploring_the_design_of_the_cortex-a15.pdf Each process is still limited to a 32-bit virtual address space, but you can have a lot more physical address space to limit page swapping to disk in virtualized environments. Regarding Federico's original question, I agree that the choice completely comes down to the workload (my personal bias notwithstanding). -Shankar _______________________________________________ Hardwarehacking mailing list [email protected] http://lists.blu.org/mailman/listinfo/hardwarehacking
