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
廬
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.
Benefits
鈥?/div>
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.
Compatible with ARM7鈩?and StrongARM
廬
The ARM920T processor is 100% user code binary compatible with
ARM7TDMI and backwards compatible with the ARM7 Thumb
廬
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:
鈥?/div>
鈥?/div>
鈥?/div>
鈥?/div>
.
WindowsCE, EPOC, Linux, and QNX operating systems
40+ Real Time Operating Systems
cosimulation tools from leading EDA vendors
variety of software development tools.
