ARM Holdings on Wednesday introduced its CoreLink CCN-504 cache coherent network technology with 1Tb/s bandwidth for the forthcoming many-core and heterogeneous multi-core/many-core system-on-chip solutions for enterprises and high-performance systems. The interconnection is compatible with both ARM Cortex-A15 processor architecture as well as next-gen ARMv8 64-bit architecture. ARM also revealed new memory controller for such chips.
As the amount of data used increases exponentially over the next 10-15 years, the CoreLink CCN-504 and DMC-520 will play an important role by providing high-performance system IP solutions for many-core applications, said Tom Cronk, deputy general manager, processor division, ARM.
CoreLink CCN-504 128-bit bus is a fully-coherent, high-performance many-core solution that supports up to 16 cores (configured as four clusters with four cores inside each one) on the same silicon die as well as up to 1Tb/s of usable bandwidth. The CoreLink CCN-504 enables system coherency in heterogeneous multi-core and multi-cluster CPU/GPU systems by enabling each processor in the system to access the other processor caches. The CoreLink CCN-504 cache coherent network includes integrated level three (L3) cache and snoop filter functions. The L3 cache, which is configurable up to 16MB, extends on-chip caching for demanding workloads and offers low latency on-chip memory for allocation and sharing of data between processors, high-speed IO interfaces and accelerators. The snoop filter removes the need for broadcast coherency messaging, further reducing latency and power. ARM plans to use CoreLink CCN on chips featuring the big.Little concept.

Arm looking to grow beyond just mobile devices.
Calxeda, LSI mentioned in the article.
ARM began when two engineers, Steve Furber and Sophie Wilson (formerly Roger Wilson), at the British company Acorn Computers Ltd, decided to design their own processor.
BTW, I came across a great beginners intro to writing a small OS in ARM assembly for the ARM based 35 dollar Raspberry Pi computer.(Cambridge University)
I, too, am a fan of the ARM architecture. And them incorporating proven supercomputer techniques like non-uniform memory access (NUMA) into multi-core products shows they know what they’re doing. The Megahertz race is over; power consumption killed that. Now, it’s cores and more cores, and techniques to make them viable.
Atmel is a nice place to get ARM chips.
They provide an excellent free IDE and C compiler.
I have not used any of the Atmel ARM chips yet but I use a lot of the AVR controllers. The same IDE has compilers for both architectures covered.
As I’m sure you know, C compilers from other suppliers are FAR from free.
