arm7
(foldoc) | ARM7
A RISC microprocessor architecture from
Advanced RISC Machines Ltd. (ARM). Building upon the ARM6
family, the goal of the ARM7 design was to offer higher levels
of raw compute performance at even lower levels of power
consumption. The ARM7 architecture is now (Dec 1994) the most
powerful low voltage RISC processor available on the market.
The ARM7 offers several architectural extensions which address
specific market needs, encompassing fast multiply and
innovative embedded ICE support. Software development tools
are available.
The ARM7 architecture is made up of a core CPU plus a range of
system peripherals which can be added to a CPU core to give a
complete system on a chip, e.g. 4K or 8K cache, {Memory
Management Unit}, Write Buffer, coprocessor interface,
ICEbreaker embedded ICE support and JTAG {boundary
scan}. The ARM710 microprocessor is built around the ARM7
core.

arm710
(foldoc) | ARM710
A 32-bit RISC microprocessor based on the
ARM7 processor core designed by Advanced RISC Machines
Ltd. The A710 is the successor to the ARM610 processor. It
was released in July 1994 by VLSI Technology Inc.
The ARM710 can run at 40MHz (fastest sample 55MHz) dissipating
500mW with a 5V supply or 25MHz with 3.3V supply. It has an 8
kilobyte on-chip cache, memory management unit and {write
buffer}.
The ARM700 and ARM710 processors represent a significant
improvement over the ARM610 processors. They have a higher
maximum clock speed and a number of architectural improvements
such as double the size of internal cache, this means that
more of any process can be executed internally without
accessing the (relatively) slow external memory. Other
improvements are an improved write buffer and an enlarged
Translation Lookaside Buffer in the MMU. All of these
improvements increase the performance of the system and
deliver more real performance than a simple comparison of
clock speeds would indicate.
The ARM710 has been optimised for integer performance. The
FPA11 floating point coprocessor has a peak throughput of
up to 5 MFLOPS and achieves an average throughput in excess
of 3 MFLOPS for a range of calculations.
