Calxeda is the company who's aim is to provide SoC for servers and the best Processors to fast cloud computing and better infrastructure...

2. Introduction
• Calxeda (previously known as Smooth-Stone) was a
company that aimed to provide computers based on the
ARM architecture for server computers.
• Calxeda claimed reduced energy consumption as well
as better cost per throughput, compared to x86-based
server manufacturers.
• Calxeda, has launched its second generation of chips
with the promise of up to twice the performance.

3. ECX-2000
 Calxeda has announced its second generation SoC, the
ARM® Cortex™ A15 based Energy Core™ ECX-2000.
 Using the ARM Cortex A15 quad-core processor, the
ECX-2000 delivers twice the performance, three times the
memory bandwidth, and four times the memory capacity
of the ground-breaking ECX-1000.
 ECX-2000 uses standard ARM Cortex™-A15 cores up to
1.8 GHz, with the integrated Calxeda Fleet Fabric, 10Gb
Ethernet, and standard I/O controllers."

4. Continue..
 The ECX-2000 also delivers the power efficiency of
ARM® processors, and the Open Stack, Linux, and
virtualization software needed for modern cloud
infrastructures.
 In addition to enhanced performance, the ECX-2000
provides hardware virtualization support via KVM and
Xen hypervisors.
 The Fleet Fabric enables the highest network and
interconnect bandwidth in the Micro Server space, making
this an ideal platform for streaming media and network-
intensive applications.

5.  ECX-2000 processes data in 32-bit chunks but it have 40-
bit virtual memory addressing so the resulting server node
can support up to 16 GB of main memory.
 While the Cortex-A15 cores can push up to 2.5 GHz,
Calxeda topped them out at 1.8 GHz to keep the thermal
envelope down.
 ECX-2000 chip had four cores, and it was etched using
well-established 40 nanometer manufacturing processes
from Taiwan Semiconductor Manufacturing Corp.

7.  A15 is basically based on ARMv7, 32 bit CPU with 40 bits
Physical Addressing.
 L1 instruction cache that is a 32 KB 2-Way set associative cache
with 64 bytes cache lines and optional parity protection per 16
bits (ECC protection per 32 bits for Data cache).
 L2 cache is of 512KB, 1MB, 2MB or 4MB configurable size, 16
Way-set associative cache with optional ECC protection per 64
bits.
 NEON data Engine is the implementation of the Advance single
instruction multiple data (SIMD) extension to ARMv7-A
Architecture.

10.  Each 32-bit chip consists of a four-core ARM Cortex-A15
package clocked from 1.1GHz to 1.8GHz, along with a dual-core
ARM Cortex-A7 processor for management services, a broad set
of I/O controllers, 10Gbps Ethernet and a beefy 4MB L2 cache.
 One of the A7 cores handles system and power management and
remote control capabilities, while the other can be programmed
by enterprises to suit their requirements.

11.  Each core on the ECX-2000 has 32 KB of L1 instruction cache
and 32 KB of L1 data cache. The ECX-2000 has 4 MB of L2
cache shared across the four cores. These are exactly the same L1
and L2 cache sizes as used in the prior ECX-1000 chips.
 Using Fleet Engines, reduce SoC cost. These engines control
the topology of the Fleet Services fabric, which can be set up
in 2D torus, mesh, butterfly tree, and fat tree network
configurations.

13. • Start with four Server Nodes
• Consumes only 20W total power
• Connected via distributed fabric switches
• Connect up to 4 SATA drives per node
• Then scale this to thousands of Server Nodes
