Freescale Semiconductor is rolling out the QorIQ 64bit platform based on Power Architecture technology featuring the e5500 core, engineered for next-generation, high-end control and data plane applications in networking, enterprise storage, security appliance, data center and aerospace/defense markets. The initial products to incorporate e5500 technology are the single-core 64bit P5010 and dual-core 64bit P5020 processors.

Delivering twice the performance of Freescale's e500 core, the e5500 architecture is designed to reach frequencies up to 2.5GHz. The platform can run either in 64bit or 32bit mode, allowing legacy software support while providing an easy transition to 64bit processing.

In addition to powering P5 level products, 64bit e5500 cores will be incorporated into future generations of QorIQ architectures. The new core includes enhancements to support many-core SoC implementations, as well as heterogeneous multicore processors which integrate StarCore and Power Architecture technologies in the same device.

"The advances we have achieved with our e5500 64bit core define the benchmark for embedded power efficiency by providing a unique combination of integration and performance within extremely aggressive power envelopes," said Lisa Su, senior VP and general manager of Freescale's networking and multimedia group. "Freescale's new e5500 platform opens up a new level of performance for multicore solutions that will power next-generation networks."

Based on the Power Architecture Instruction Set (ISA) v2.06 and designed for compatibility with future generations of QorIQ products, e5500 technology features:

??A 7-stage pipeline with out-of-order execution;
??Increased flat addressable memory space up to 64GB;
??High-performance classic floating point unit supporting IEEE 754 floating point operations;
??Hybrid 32bit mode to support legacy software and transition to 64bit architecture;
??L1 cache, backside L2 cache plus shared L3 cache

The new P5020 and P5010 processors offer Freescale's highest single-threaded performance for next-generation embedded control plane applications. With frequencies scaling to 2.2GHz, the P5020 delivers an impressive 13,200 DMIPS in 30W. Both devices are pin-compatible with P4 and P3 platform products to provide seamless roadmap scalability from two 2.2GHz cores up to four and eight 1.5GHz cores.

Manufactured in 45nm process technology, the P5020 and P5010 devices integrate new intellectual property. A RAID 5/6 engine accelerates parity calculations for storage applications, making it ideal for enterprise storage area networks and enterprise network attached storage solutions. An upgraded Serial RapidIO (v1.3 + 2.1) supports higher bandwidth, and a message manager introduces support for Type 9 (data streaming) and improves Type 11 (messaging) transactions. The P5020 also offers integrated SATA 2.0, PCI-E Gen 2 controllers, 10 Gigabit Ethernet, 5x SGMII/2.5Gbit/s SGMII, and two USB 2.0 with integrated PHYs, to provide a highly integrated, high-performance processor suitable for networking, industrial and data center applications.

While many current 32bit systems have become memory bound, the P5020 increases the flat addressable memory space to 64GB. For industrial customers requiring additional floating point performance, the P5020 offers an IEEE Standard 754 floating point unit, providing 2x single precision and 4x floating point performance over previous e500 products.

Freescale enables a wide ecosystem of third-party software to simplify product development and speed time to market. Customers can start their 64bit designs prior to first silicon with simulation platforms and CodeWarrior tools. 32bit and 64bit software solutions are expected to be available from a broad set of ecosystem partners including Enea, Green Hills, Mentor Graphics, Wind River, CodeSourcery, QNX and others. Freescale VortiQa application software is also planned for P5 platform products.

Simulated models of the P5020 and P5010 are planned for availability in July. Initial samples are planned for availability in Q4 10, and qualification is expected in 2H 11.
