SuperH Announces Record-Breaking Benchmark Scores for SH4-202 RISC CPU Core

SH4-202 optimized benchmark results for EEMBC

23 April, 2003 - SuperH, Inc., the leading supplier of multimedia RISC CPU cores, today announced that it has received outstanding scores from the Embedded Microprocessor Benchmark Consortium (EEMBC) for its SH4-202 RISC CPU core family.

The SH4-202 was tested against EEMBC benchmark suites that represent the performance of embedded processors in automotive/industrial and consumer applications. Under optimized test conditions with EEMBC benchmark source code optimized using assembly coding, the SH4-202 received record breaking scores of 1.15378 Automarks and .20483 Consumermarks per MHz.

The benchmark scores were obtained in a cycle-accurate, 266-MHz simulation using the open-source GNU gcc 3.2.1 Vienna 1.3 beta compiler.

"Our Full Fury scores for the SH4-202 demonstrate the unleashed potential of the SH-4 core and its high-performance 4-way vector FPU, which enable a whole new category of advanced graphics and video applications for consumer embedded systems," said Rick Chapman, VP of Marketing & Sales at SuperH, Inc. "These new scores provide a further validation of our architecture while providing a significant measure of processor performance according to standards that the industry has agreed upon."

CPU cores in the SH-4 family are based on a 32-bit SuperH RISC core available as a soft core or a range of hard cores optimized for different silicon processes. The published EEMBC scores are benchmarked on the SH4-202 with 2-way, 32-KB data and 16-KB instruction caches. System-on-chip products based on the SH-4 core utilize the SuperHyway™, a configurable on-chip memory-mapped split-transaction packet-routing interconnect capable of supporting high-bandwidth and low-latency transactions.

"These certified EEMBC benchmark scores have allowed SuperH to credibly demonstrate the performance benefits of its SH-4 architecture," said Markus Levy, EEMBC president. "SuperH is also the first EEMBC member to provide optimized scores for a device using the EEMBC automotive/industrial benchmark suite, which demonstrates the company's commitment to this market segment."
