High-Performance ARM920T Processor Core
The EP9315 features an advanced
ARM920T processor design with an
MMU that supports Linux
CE
operating systems. The ARM920T’s 32-
bit microcontroller architecture, with a
five-stage pipeline, delivers impressive
performance at very low power. The
included 16 KB instruction cache
and 16 KB data cache provide zero-
cycle latency to the current program
and data, or can be locked to provide
guaranteed no-latency access to critical
instructions and data. For applications
with instruction memory size restrictions,
the ARM920T’s compressed Thumb
instruction set provides a space-
efficient design that maximizes external
instruction memory usage.
MaverickCrunch™ Math Engine for Ultra-Fast
Math Processing
The MaverickCrunch engine is
an advanced mixed-mode math
coprocessor that greatly accelerates the
single and double-precision integer and
floating-point processing capabilities
of the ARM920T processor core.
The engine simplifies the end-user’s
programming task by using predefined
coprocessor instructions, by utilizing
standard ARM compiler tools, and by
requiring just one debugger session
for the entire system. Furthermore, the
integrated design provides a single
instruction stream and the advantage
of zero latency for cached instructions.
To emulate this capability, competitors’
solutions add a DSP to the system,
which requires separate compiler/linker/
debugger tool sets. This additional
DSP requires programmers to write two
separate programs and debug them
simultaneously, which can result in
frustration and costly delays.

, and many other embedded
®
, Windows

The single-cycle integer multiply-
accumulate instruction in the
MaverickCrunch engine allows the
EP9315 to offer unique speed and
performance while encoding digital
audio and video formats, processing
data via Ethernet, and performing other
math-intensive computing and data-
processing functions in consumer and
industrial electronics.
Graphics Accelerator
The EP9315 contains a hardware
graphics acceleration engine that
improves graphic performance by
handling block copy, block fill and
hardware line draw operations. The
graphics accelerator is used in the
system to offload graphics operations
from the processor.
PCMCIA Interface
The PCMCIA interface supports
two 8-bit or one 16-bit PCMCIA PC
card. These devices are credit-card-
sized peripherals that add memory,
mass storage, and I/O capabilities to
computer systems, and can be used
to further broaden the options of a
designer’s platform.
MaverickKey™ Unique ID Secures Digital
Content and OEM Designs
MaverickKey unique hardware
programmed IDs provide an excellent
solution to the growing concern over
secure Web content and commerce. With
Internet security playing an important
role in the delivery of digital media such
as books or music, traditional software
methods are quickly becoming unreliable.
The MaverickKey unique IDs provide
OEMs with a method of utilizing specific
hardware IDs for DRM (Digital Rights
Management) mechanisms.
Both a specific 32-bit ID as well as a
128-bit random ID is programmed into
the EP9315 through the use of laser
probing technology. These IDs can then
be used to match secure copyrighted
content with the ID of the target device
that the EP9315 is powering, and then
deliver the copyrighted information over
a secure connection. In addition, secure
transactions can benefit by matching
device IDs to server IDs.
MaverickKey IDs can also be used by
OEMs and design houses to protect
against design piracy by presetting
ranges for unique IDs. For more
information on securing your design
using MaverickKey, please contact your
Cirrus Logic sales representative.
Integrated Three-port USB 2.0
Full Speed Host with Transceivers
The EP9315 integrates three USB 2.0
Full Speed host ports. Fully compliant
to the OHCI USB 2.0 Full Speed
specification (12 Mbps), the host ports
can be used to provide connections to
a number of external devices including
mass storage devices, external
portable devices such as audio players
or cameras, printers or USB hubs.
Naturally, the three-port USB host
also supports the USB 2.0 Low Speed
standard. This provides the opportunity
to create a wide array of flexible
system configurations.
Support for a Wide Array of Display
Interfaces with a Flexible Raster Controller
The EP9315 processor provides
timing and interface signals for digital
LCD, TFT, and CRT displays. It is
fully programmable for either non-
interlaced or dual-scan color and
grayscale flat panel displays, with up
to 18 bits-per-pixel of color resolution.
