ARM Aims at Intel, Cortex A15 Headed for Smartphones, Notebooks and Servers

Last month TI announced it was the first to license ARM’s next-generation Eagle core. Today, ARM is announcing the official name of that core: it’s the ARM Cortex A15. Architectural details are light, and ARM is stating that first silicon will ship in 2012 at 32/28nm. Here’s what we do know. The Cortex A15 will be a multi-core CPU, designs can have as few as a single core but most will have 2 - 4 cores depending on their target market. The cores will all be superscalar out-of-order designs and support Long Physical Address Extensions (greater than 32-bit memory addressing). I suspect the cores will be an evolution of the Cortex A9. The Cortex A15 will support a new instruction set which ARM is calling ARMv7-A. The additional instructions will enable hardware virtualization support. The Cortex A15 will feature private L1 caches but a shared L2 cache (similar to the A9). The L2 cache is stated to be low latency and up to 4MB in size, although smartphones will probably see smaller versions. ARM is promising FP and SIMD performance improvements, but it isn't saying anything more than that.  Read on for more on ARM's plans for the Cortex A15.
