ARM710

processor 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 writebuffer.

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.
