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
thedatacenter 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 solutionsusing this new ARM CoreLink technology, and think
we will once againsend 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.

“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. “This ensures quality
of service and coherent operation across the system, and enables SoC designers
to efficiently prioritize and handle wide data flows with optimum latency.”

The CoreLink CCN-504 supports both the current-generation high-end Cortex-A15
processor and future ARMv8 processors and is the first in a family of
network-based interconnect products planned by ARM. Building on the success of
the AMBA® 4 ACE™ specification the CoreLink CCN-504 also benefits from ARM
experience in hardware-based coherency, which enables improved
energy-efficiency and lower latency than software coherency. Over 8000 AMBA 4
ACE specifications have been downloaded to date.

The CoreLink CCN-504 cache coherent network includes integrated level 3 (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.

Availability: the ARM CoreLink CCN-504 cache coherent network is available to
lead licensees now, and sampling in partner products in 2013.
