SuperH Announces Record-Breaking Scores for 64-bit SH-5 RISC CPU Core; SH-5 'Out-of-Box' and 'Consumer Optimized' Benchmark Results
SAN JOSE, Calif. & BRISTOL, England & TOKYO—(BUSINESS WIRE)—Feb. 17, 2004—
SuperH, the leading supplier of multimedia RISC CPU
cores, today announced that it has received outstanding certified
scores from the Embedded Microprocessor Benchmark Consortium (EEMBC)
for its SH-5 64-bit RISC CPU core family, delivering the highest-ever
optimized ConsumerMark(TM) score for a 64-bit CPU core.
The SH-5 was benchmarked across the complete range of EEMBC's
application benchmark suites and optimized for the Consumer benchmark
suite, clearly demonstrating the benefits of using a 64-bit CPU for
multimedia applications.
'Out of Box' Benchmark SH-5 Score / MHz
-------------------------------------------------
ConsumerMark 0.09153
-------------------------------------------------
AutoMark(TM) 0.58931
-------------------------------------------------
NetMark(TM) 0.01637
-------------------------------------------------
OAMark(TM) 0.83262
-------------------------------------------------
TeleMark(TM) 0.01429
-------------------------------------------------
'Optimized' Benchmark SH-5 Score / MHz
-------------------------------------------------
ConsumerMark 0.32965
-------------------------------------------------
Compared with out-of-the-box results, benchmark tests performed
under optimized conditions show an up to five times speed-up of
applications such as JPEG codecs. Optimizations were achieved using
the SH-5's 8-way SIMD instruction set.
The SH-5 results were generated using the SuperH GNU C toolchain
and cycle accurate simulator. The CPU core used in these benchmarks
includes a 64-bit CPU with 2, 4 and 8-way SIMD instruction set, vector
floating point unit and MMU. The CPU core is a tiny 2.9mm2 in a
generic 0.13um CMOS process. With the memory configuration used in
these benchmarks of 32K instruction and 32K data caches, the complete
core measures only 9.8mm2.
"The SH-5 has been designed for programmable multimedia
applications and the optimized EEMBC benchmark results clearly
demonstrate the benefits of our rich SIMD instruction set," said
Atsushi Hasegawa, VP of Worldwide Engineering at SuperH, Inc. "We
exploit the 64-bit architecture to deliver 8-way SIMD, and at less
than 3mm2 the SH-5 CPU core is competitive with 32-bit offerings from
other companies."
Markus Levy, EEMBC president, commented "With these scores SuperH
maintains its position as one of the leading CPU companies benefiting
from the complete range of EEMBC benchmarks that independently
validate the true application performance of its architecture."
The SH-5 RISC CPU core is available now as a synthesizable or hard
macro for a range of silicon processes and can be implemented at
speeds up to 600MHz in a 0.13um process. The SH-5 core includes a full
memory management unit and can run a range of operating systems
including Linux and Windows CE.NET.
