LTE and WiMAX Baseband
The P2020 and P2010 communications
processors are well-suited for Long-Term
Evolution (LTE) and WiMAX channel card
applications. There are two factors that drive
the need for dual-core performance without
breaking out of a single-core power budget:
• Increased bandwidth per subscriber
• Flattening of the infrastructure hierarchy
Together, these factors increase the
processing requirements of the channel
card. P2 series processors, with dual-
core performance in single-core power
budgets, can increase performance in Layer
2 baseband processing and implementing
network interfaces.
Layer 2 baseband processing implements
the RLC layer that controls the base station
and subscriber access to air interface
resources. The advanced QoS features of the
Gigabit Ethernet ports assist in scheduling
these resources. This Layer 2 processing
includes the medium access control
(MAC), which controls the base station and
subscriber access to air interface resources.
Resources are scheduled according to QoS
requirements using packet concatenation
and segmentation, retransmission through
automatic repeat request (ARQ) and
hybrid automatic repeat request (HARQ) in
combination with Layer 1.
Typically backhaul is implemented with
either dual Gigabit Ethernet on SGMII (for
redundancy) or Serial RapidIO interface, both
of which are supported in the QorIQ P2 series
processors. The Serial Rapid IO interface also
allows direct connection to the DSPs—such
as Freescale’s MSC8144 and MSC8156 four-
and six-core DSPs—that implement the Layer
1 processing. The security block handles the
secure network termination requirement.
This solution performs network backhaul
transport and interworking with internal
interfaces. This includes processing the
network layers up to OSI Layer 3, including
IPsec secure network termination, header
compression and traffic classification
(QoS). The network interface card (NIC)
can optionally support 3G LTE radio link
encryption—however, depending upon the
selected architecture, this could be partitioned
to the channel card.

Compute Blades
Blade servers have been widely adopted in
data centers because they cost less to deploy
and less to operate—due to savings in power
and cooling—than rack-optimized servers.

Blade servers are also more easily scaled
than fixed-capacity monolithic servers to meet

improved power and cooling efficiency and

As enterprises begin to migrate to next-
AMC Connector
generation data centers, blade server switches
are evolving to meet the new demands with
advanced functions such as application-aware
networking, low latency line-rate switching
at Gigabit (Gb) speeds, advanced QoS,
support for virtualization and advanced
security features.
QorIQ processors can help designers reap the
benefit of using highly integrated processors
with the I/O needed for application/content-
aware processing. Freescale partner
companies such as 6WIND provide an open
framework to ease the transition from a
single core to many cores. Multicore-aware
network middleware from 6WIND can boost
performance, placing configuration and
management at the heart of the software. This
solves real business issues of time and cost
savings associated with software integration,
interface, configuration and network
management of multicore machines.
The P2020 processor can manage control
and dataplane functions in blade systems.
This reduces the cost of integrating additional
bridge chips to perform these functions.

Networking
Features for the Market:
• SD/MMC interface enables modularity by
supporting booting from flash cards
• PCI Express interfaces enable multiple
flexible I/O options
• USB port for front-panel code uploads
when connecting directly to a PC for
maintenance
• Triple Gigabit Ethernet (dual on SGMII for
redundancy for backplane interconnect)
and one Gigabit Ethernet interface for
high-performance debug and maintenance
The primary functions of a linecard
controller are:
• Exception handling: Packets that cannot be
interpreted by the typically more hardwired
datapath are kicked up to the control
plane processor. These may be older or
esoteric protocols which are not worth
accommodating in ASICs, but can be
handled with software with low performance
impact because they occur infrequently.
• Board housekeeping: The control plane
processor may be used to configure,
provision and control other devices on the
board. It also will collect statistics. It can
implement a command line interface.
• Table maintenance: A line card controller
may, especially in a distributed system,
manage the forwarding tables. The tables
are created by implementing a variety of
interior routing protocols (such as Open
Shortest Path First or Routing Information
Protocol) and external routing protocols
(such as Border Gateway Protocol). The
tables are then exported to the forwarding
path for per-packet access.
In the case of centralized processing, these
functions are performed by a centralized
processor, which can tolerate higher power
and associated increased cooling costs
because there are fewer of those cards per
system. In these cases, the line card has little
intelligence.
Implementing a line card in a distributed
processing system provides several
advantages. You may be able to forgo
the costly centralized services card,
which consumes a valuable slot in the
chassis. You have the opportunity to
perform local switching at the line card, thus
conserving system resources. And the system
becomes more scalable—as you add a line
card, you automatically get the increased
processing that it requires. However, in
this system, the costs of high-volume line
cards are critically important. Because of
that, thermal budgets are very tight. The
need for high performance at low power is a
requirement that the P2 family fulfills.
Applications:
• Line card controller
• Mid-range line card control plane
• Low-end line card combined control and
data plane
• Shelf controller
Line Card Control Plane for
Enterprise Routers
One of the primary applications for the QorIQ
P2020 communications processor is as a line
card control plane processor. Typically the
P2020 will sit to the side of the main datapath,
which has I/O processors on the front panel
connected to a backplane interface device.
The P2020 processor will communicate with
these components using standard interfaces
such as PCI Express or the local bus. The
P2020 will often have front panel interfaces as
well. One Gigabit Ethernet interface may be
used for high-performance debug: the DUART
can be used for a low-level command line
interface and the USB port may be used for
front-panel code uploads when connecting
directly to a PC for maintenance. Redundant
Gigabit Ethernet ports to the backplane are
used as a management interface, which can
be used to communicate with a centralized
resource for receiving table updates, for
instance. The eSDHC interface enables
modularity by supporting booting from
flash memory cards.

Multiservice Routers
A multiservice router or business gateway
requires a combination of high performance
and a rich set of peripherals to support the
datapath throughputs and required system
functionality. The P2 series of single- and
dual-core devices offer a scalable platform to
develop a range of products that can support
the same feature set. Integrated 10/100/1000
Ethernet controllers with classification and
QoS capabilities are ideal for managing
the datapath traffic between the local area
network (LAN) and wide area network (WAN)
interface. PCI Express ports can provide
connectivity to IEEE
®
802.11n radio cards
for wireless support and TDM for legacy
phone interfaces to support voice. USB or
eSDHC interfaces can be used to support
local storage; the second USB interface
is also available to support USB-attached
printers or as a console port. The integrated
security engine can provide encrypted secure
communications for remote users with
VPN support.
