To address the significant increase in data over the next 10-15 years, and the demand for more energy-efficient network infrastructure and servers, ARM has announced the ARM® CoreLink™ CCN-504 cache coherent network. This advanced system intellectual property (IP) can deliver up to one terabit of usable system bandwidth per second. It will enable SoC designers to provide high-performance, cache coherent interconnect for ‘many-core’ enterprise solutions built using the ARM Cortex™-A15 MPCore™ processor and next-generation 64-bit processors.
LSI, a leading designer of intelligent semiconductors that accelerate storage, mobile networking and client computing, and Calxeda, an innovative supplier of disruptive SoC technology for the server market, are lead licensees for the CoreLink CCN-504 launch.
ARM has also unveiled the new ARM CoreLink DMC-520 dynamic memory controller that has been designed and optimized to work with the CoreLink CCN-504. The new dynamic memory controller provides a high-bandwidth interface to shared off-chip memory, such as DDR3, DDR3L and DDR4 DRAM. It is part of an integrated ARM DDR4 interface solution incorporating ARM Artisan® DDR4/3 PHY IP planned for introduction in 2013.
“Calxeda and ARM have been working closely to meet the demands of the datacenter since ARM's initial investment in our company in 2008, and we are beginning to see the fruits of that relationship,” said Barry Evans, co-founder and CEO, Calxeda. “We are already building our next generation datacenter-class solutions using this new ARM CoreLink technology, and think we will once again send shockwaves across the industry when they are announced.”“To meet the demands of rapidly growing mobile network traffic, LSI and ARM have worked closely to drive a feature-rich on-chip interconnect that can serve as the backbone for industry-leading many-core system-on-chip devices,” said Gene Scuteri, vice president of engineering, LSI. “ARM expertise in processor and interconnect technology, guided by LSI's deep understanding of networking and compute workloads, has delivered a robust, carrier-grade interconnect that will deliver scalable, deterministic performance and quality of service for today’s most advanced networks.” CoreLink CCN-504 is the first in a family of products. It enables a fully-coherent, high-performance many-core solution that supports up to 16 cores on the same silicon die. The CoreLink CCN-504 enables system coherency in heterogeneous multicore and multi-cluster CPU/GPU systems by enabling each processor in the system to access the other processor caches. This reduces the need to access off-chip memory, saving time and energy, which is a key enabler in systems based on ARM big.LITTLE™ processing, a new paradigm that can deliver both high-performance, required for content creation and consumption, and extreme power efficiency for extended battery life.
