ARM Confidential - Draft
Applications
• Applications running a
platform OS:
- EPOC
- Linux
- WindowsCE
• High performance wireless
applications:
- Smart phones
- PDAs
• Networking applications
• Digital set top boxes
• Imaging
• Automotive control
solutions
• Audio and video encoding
and decoding
Benefits
• Designed specifically for
System-On-Chip
integration
• Supports the Thumb
instruction set offering the
same excellent code
density as the ARM7TDMI.
• High performance allows
system designers to
integrate more functionality
into price and
power-sensitive
applications demanding
more performance
• Cached processor with an
easy to use lower
frequency on-chip system
bus interface.
The ARM920T™
The ARM920T is a a high-performance 32-bit RISC integer processor
macrocell combining an ARM9TDMI™ processor core with:
• 16KB instruction and 16KB data caches
• instruction and data Memory Management Units (MMUs)
• write buffer
• an AMBA™ (Advanced Microprocessor Bus Architecture) bus interface
•an Embedded Trace Macrocell (ETM) interface.
High performance
The ARM920T provides a high-performance processor solution for open
systems requiring full virtual memory management and sophisticated memory
protection. An enhanced ARM
®
architecture version 4 MMU implementation
provides translation and access permission checks for instruction and data
addresses.
The ARM920T high-performance processor solution gives considerable
savings in chip complexity and area, chip system design, and power
consumption.
Compatible with ARM7™ and StrongARM
®
The ARM920T processor is 100% user code binary compatible with
ARM7TDMI and backwards compatible with the ARM7 Thumb
®
Family and
the StrongARM processor families, giving designers software-compatible
processors with a range of price/performance points from 60 MiPS to 200+
MIPS. Support for the ARM architecture today includes:
• WindowsCE, EPOC, Linux, and QNX operating systems
• 40+ Real Time Operating Systems
• cosimulation tools from leading EDA vendors
• variety of software development tools.
