EEMBC Publishes New Scores for IBM’s PowerPC 405GPr and 440GP Processors

IBM 440GP Sets EEMBC Benchmark Record for SoCs in Four Application Categories

EL DORADO HILLS, Calif.—February 25, 2003—New ECL-certified benchmark scores for the IBM PowerPC 440GP embedded processor have broken records for system-on-chip devices tested by EEMBC, the Embedded Microprocessor Benchmark Consortium.

In out-of-the-box tests using the Green Hills Software Multi 3.6.1 compiler, the new 500-MHz 440GP scores show an improvement of as much as 17% compared with IBM’s prior certified scores for this device. The results demonstrate an improvement in compiler capability effecting a more efficient use of the processor’s architecture.

EEMBC is also publishing ECL-certified scores for the IBM PowerPC 405GPr embedded processor, which too was certified using the Green Hills Software compiler.

EEMBC Benchmark Suite	IBM 266-MHz 405GPr	IBM 400-MHz 405GPr	IBM 500-MHz 440GP	Consolidated scores units
Networking	4.0	5.5	9.4	Netmarks
Telecom	4.7	7.1	11.4	Telemarks
Consumer	20.1	29.1	42.5	Consumermarks
Automotive/Industrial	102.3	152.0	264.2	Automarks
Office Automation	213.6	317.4	511.1	OAmarks

“Clearly, our customers see value in these benchmarks and use them to make design decisions,” said Lisa Su, director of PowerPC and emerging products, IBM Microelectronics. “We are pleased with results of this latest benchmark and the scores for the IBM 440GP PowerPC. In addition to our standard products and ASICs, with our recent launch of PowerPC licensing and support initiatives, more customers can now leverage PowerPC performance advantages in their own product designs.”

Manufactured in IBM’s advanced 0.18-micron CMOS SA-27e copper process technology, the IBM PowerPC 440GP combines the PowerPC 440 core with a high-bandwidth on-chip CoreConnect bus that provides separate read and write data busses to deliver 4.2 GB/s of on-chip peak bandwidth. The core’s large data cache (32 KB) and instruction cache (32 KB) are 64-way set-associative, with versatile configurations to enhance performance tuning.

“As a founding member of EEMBC, IBM continues to support this consortium in many ways, and publishing scores for both its PowerPC 405GPr and 440GP processors is one of those ways,” said EEMBC President Markus Levy. “IBM also supports EEMBC by chairing the Office Automation subcommittee, helping to set new standards for measuring processor performance in applications that include multifunction printers and scanners.”

The IBM PowerPC 405GPr embedded processor is a pin-compatible upgrade to the 405GP. Based on IBM’s 0.18-micron SA-27e copper process technology, the 405GPr offers speeds of 266, 333, and 400 MHz; a larger data cache than the 405GP; and typical power dissipation of 1.3 watts for the 333 MHz processor.
