QorIQ Communications Platforms
P4 Series Multicore Processors
Overview
Freescale QorIQ communications platforms are the next-generation evolution
of our leading PowerQUICC communications processors. Built using high-
performance Power Architecture
®
cores, QorIQ platforms enable a new era of
networking innovation where the reliability, security and quality of service for
every connection matters.
QorIQ P4080 Multicore Processor
The QorIQ P4080 multicore processor, the
first product offered in the QorIQ P4 platform
series, delivers industry-leading performance
in the under 30-watt power category. It
combines eight Power Architecture e500mc
cores operating at frequencies up to 1.5 GHz
with high-performance datapath acceleration
logic, as well as networking I/O and other
peripheral bus interfaces. The P4080, built
in 45 nm technology, is designed to deliver
high-performance, next-generation networking
services in a very low power envelope.
The QorIQ P4080 processor is designed for
combined control and dataplane processing,
enabling high-performance layers 2–7
processing. Its high level of integration offers
significant performance benefits compared to
multiple discrete devices, while also greatly
simplifying board design.

Basic Peripherals and Interconnect
The processor is well suited for applications
that are highly compute intensive, I/O
intensive or both. This makes it ideal for
applications such as enterprise and service
provider routers, switches, media gateways,
base station controllers, radio network
controllers (RNCs), access gateways for
long-term evolution (LTE) and general-
purpose embedded computing systems in
the networking, telecom, industrial, aerospace
and defense markets.
Advanced virtualization technology brings a
new level of hardware partitioning through
an embedded hypervisor that allows system
developers to ensure software running on any
CPU only accesses the resources (memory,
peripherals, etc.) that it is explicitly authorized
to access. The embedded hypervisor enables
safe and autonomous operation of multiple
individual operating systems, allowing them to
share system resources, including processor
cores, memory and other on-chip functions.

Key Features
Freescale delivers a groundbreaking three-
tiered cache hierarchy on the QorIQ P4
platform. Each core has an integrated level 1
(L1) cache as well as a dedicated level 2 (L2)
backside cache that can significantly improve
performance. Finally, a multi-megabyte level 3
(L3) cache is also provided for those tasks for
which a shared cache is desirable.
The CoreNet coherency fabric is a key design
component of the QorIQ P4 platform. It
manages full coherency of the caches and
provides scalable on-chip, point-to-point
connectivity supporting concurrent traffic to
and from multiple resources connected to the
fabric, eliminating single-point bottlenecks
for non-competing resources. This eliminates
bus contention and latency issues associated
with scaling shared bus/shared memory
architectures that are common in other
multicore approaches.
The QorIQ P4080 multicore processor is
extremely flexible and can be configured
to meet many system application needs.
The processor’s e500mc cores, leveraging
advanced virtualization technology, can work as
eight symmetric multiprocessing (SMP) cores,
or eight completely asymmetric multiprocessing
(AMP) cores, or they can be operated with
varying degrees of independence with a
combination of SMP and AMP groupings. Full
processor independence, including the ability
to independently boot and reset each e500mc
core, is a defining characteristic of the device.
The ability of the cores to run different operating
systems (OS), or run OS-less, provides the user
with significant flexibility in partitioning between
control, datapath and applications processing.
It also simplifies consolidation of functions
previously spread across multiple discrete
processors onto a single device.
Ecosystem and Developer
Environment
Developers creating solutions with Power
Architecture technology have long benefited
from a vibrant support ecosystem, including
high-quality tools, OSes and network protocol
stacks. Freescale has collaborated with our
partners on the QorIQ P4080 processor to
continue our strong ecosystem heritage. This
helps to ensure that the best enablement
tools are available to cost-effectively meet the
unique development challenges of multicore
architectures and speed your time to market.
To this end, Freescale has partnered with
Virtutech to offer a robust, innovative hybrid
simulation environment that provides a
controlled, deterministic and fully reversible
environment for the development, debugging
and benchmarking of software for complex
multicore-based architectures. The hybrid
simulator combines Virtutech’s fast, functional
Simics™ model, with a detailed performance
model of the platform. This combination
enables fast hardware concept testing and
evaluation, as well as performance verification
and helps accelerate your development cycle,
provide more flexible debug capability and
improve the overall quality of your software.
Freescale has also engineered capabilities
into the QorIQ P4080 to enable advanced
debugging while working in tandem with
its ecosystem partners to assure availability
of tools that can take advantage of these
features. These capabilities include integrated
instruction trace, watchpoint triggers, cross-
event triggers, performance monitoring and
other debug features as defined by the
Power
®
ISA. These features enable dynamic
debug essential for providing visibility into
complex interactions that may occur among
tasks running on different cores.

The P4080 was the flagship product for the
QorIQ family when it was first introduced to
the market. It provided the foundation upon
which the P5, P3, P2 and P1 processor
families were built. In addition, the P4 series
expanded its portfolio with the P4040 and
P4081 communications processors. These
processors provide the performance, power
and price necessary to meet a broad spectrum
of high-performance applications. The P4040
is pin-for-pin compatible with the P4080
processor, providing the same I/O functionality
and frequency as the P4080 but with fewer
cores. This is designed to provide the user with
a smaller power envelope footprint.
The P4081 addition brings high-performance
computing to a broader spectrum of
applications. Like the P4040, it is pin-for-pin
compatible to both the P4080 and P4040. It
contains eight cores, with each core capable
of supporting 1.2 GHz. At attractive price
and power points, this device expands the
possibilities of applications for high-performance
computing.
