High-Performance ARM920T Processor Core
The EP9302 features an advanced
ARM920T processor design with an MMU
that supports Linux
many other embedded 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
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.

The single-cycle integer multiply-accumulate
instruction in the MaverickCrunch engine
allows the EP9302 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.
Integrated Five-Input,
Multiplexed A/D Controller
The EP9302 integrates a signed 12-bit
analog-to-digital converter with a multi-
plexed front-end that is controlled through
a software-configured switch matrix. This
matrix allows routing of the five input
signals to the A/D sample input or to the
+REF and -REF inputs. If external REF
inputs are not required, the A/D REF
inputs can be internally switched to VDD
and GND allowing all five inputs to be
sampled. Reading a sampled result
enables a convert command for the next
sample. These capabilities are especially
useful in process control and instrumen-
tation applications as well as voltage or
temperature monitoring.
