Freescale showcases quad-core i.MX6 processor

Written by Fudzilla staff


Four Cortex A9 cores and a 64-bit memory bus
Freescale has showcased its first quad-core processor, the i.MX6, based on four Cortex A9 cores. The i.MX6 series will also feature single and dual-core processors.

The chipmaker promises to be among the first companies to offer quad-core ARM processors, but still the i.MX6 won’t show up in actual products until 2012. The i.MX6 features a 64-bit memory bus and new graphics core capable of delivering dual-stream 1080p H.264 video decoding. It also features “console-style” 3D graphics with 200MT/s and a separate 2D engine for UI acceleration.

Freescale is working to make the processor compatible with all major operating systems, including Android, Linux and ARM-compatible Windows variants.

1.2Ghz, quad@ 350mW running 1080p video .. looks nice.

What's with the 64b memory controller though? The cores can't access that

at first glance I see 128bit :) but then I see also SIMD, which is a way to pack multiple registers into a single instruction, a little like AMD does with it's 256b FP pcking 2x128.

see http://processors.wiki.ti.com/index.php/Cortex-A8_Features#NEON:_Advanced_SIMD - it isnt obvious that neon ever looks past it's own registers - so Id guess it must only talk to l2 cache. that means it has the same main-memory controller as the rest of the cortex a9, which is 32 bit.
