CoreMP7
ARM7 Family Processor
CoreMP7 is a general purpose, 32-bit, ARM7 family
microprocessor that offers high performance and low
power consumption. The ARM architecture is based on
Reduced Instruction Set Computer (RISC) principles. The
simplicity of RISC results in a high instruction throughput
and fast real-time interrupt response from a small and
cost-effective processor core. Pipeline techniques are
employed so that all parts of the processing and memory
systems can operate continuously. Typically, while one
instruction is being executed, its successor is being
decoded, and a third instruction is being fetched from
memory. The CoreMP7 processor also implements the
Thumb instruction set, which makes it ideally suited to
high-volume applications with memory restrictions, or
applications where code density is an issue.
The 16-bit Thumb instruction set approaches twice the
density of standard ARM code while retaining most of
the ARM performance advantage over a traditional
16-bit processor using 16-bit registers. This is possible
because Thumb code operates on the same 32-bit
register set as ARM code. Thumb code is able to reduce
up to 65% of the code size compared to 32-bit ARM
instructions, and offers 160% of the performance of an
equivalent ARM processor connected to a 16-bit memory
system.
Device Utilization
CoreMP7 is available with and without debug for use in
each ARM-enabled device. These variants (Core only or
Core plus debug) are available in CoreConsole and are
easily selected from the core configuration menus. The
utilization and performance of the variants for each
device are shown in Table 1.
Core Only
This variant of the CoreMP7 is optimized for maximum
speed and minimum size and does not include debug.
Core Plus Debug
This variant of the CoreMP7 is optimized for minimum
size and includes debug.
