IBM Corp. has unveiled what it claims to be the highest performance, highest throughput processor for SoC product families in the communication, storage, consumer, and aerospace and defense markets.

LSI Corp. has collaborated with IBM on the development of the processor core, called the PowerPC 476FP. LSI intends to utilize the 476FP PowerPC core in its next-generation multicore platform architecture for networking applications, .

The PowerPC 476FP operates at clock speeds in excess of 1.6GHz, and 2.5 Dhrystone MIPS per MHz, delivering over 2x the performance of IBM's most advanced embedded core currently available for the OEM market. This level of performance also positions the 476FP as the highest performing embedded processor for SoC designs yet announced and available in the industry.

The processor extends the scalability of IBM's Power Architecture in traditional embedded applications, and provides a growth platform for emerging applications such as 4G networks and WiMAX infrastructure products.

The processor dissipates just 1.6W at these performance levels when fabricated in IBM's 45nm silicon-on-insulator (SOI) technology, positioning the 476FP as one of the most energy efficient embedded processor cores in the industry.

The 476FP offering includes an architectural extension of IBM's CoreConnect local bus technology (PLB6), supporting coherency for multiple processors and providing a level of scalability that is ideal for customers designing families of products and focusing on software re-use. The 476FP also provides a seamless performance boost to all customers currently using the PowerPC 4xx family of processor cores, maintaining IBM's long-standing practice of protecting legacy software investments.

"This high-performance, power efficient, compact processor core allows customers to meet the needs of today's applications, while preserving legacy code.," said Richard Busch, IBM director of ASIC products. "Our collaboration with LSI brings together IBM's expertise in processor development with LSI's experience in networking and storage architectures, optimizing this core to address today's high-speed embedded requirements."
