[BitTech] ARM announces first 28nm Cortex-A15 hard macro

Finally, it's the first hard macro to feature the ARMv7-based Cortex-A15 'Eagle' IP. Unlike ARM's previous chips, the Cortex-A15 boasts a wealth of impressive functionality which makes it suitable for use outside the traditional embedded and mobile markets. Support for greater than 4GB of RAM and hardware virtualisation technologies indicates ARM's desire to attack the microserver and cloud computing markets, although at present the chip is still a 32-bit part - albeit one with 48-bit memory addressing.

The particular design announced by ARM ahead of its formal unveiling at the Cool Chips conference today boasts a 2GHz clock speed, a pair of 32KB L1 caches - shared between two cores - and a single shared 2MB L2 cache, 224 interrupts, six power domains, and support for the AMBA protocol for on-chip interconnections in multi-processor implementations.

2GHz quad-core with 128GB+ memory support, virtualization, and chip-to-chip communication.... all ready to go.

Not bad. DDR4?

ARM is so close to having its foot so far in the door it won't ever close.

I for one would love to see them take reign in cloud computing and servers.. Intel would be forced to step up even more.

Yes, although I'm curious to know if anything has changed with this A15, especially considering its target market.

There's no need for DDR4 unless it's insanely slowly clocked to conserve power. Performance isn't the major concern here.
