Low-power quad-core microprocessor

25 November 2009 DSP, Micros & Memory

Freescale Semiconductor is expanding the range of power and performance options available for its QorIQ family of multicore platforms with the introduction of the QorIQ P4040 processor.

A four-core version of Freescale’s flagship P4080 processor, the new device delivers low-power solutions for applications requiring high performance in a sub-15 Watt typical power envelope. Pin and code compatibility with the eight-core P4080 device allows customers to migrate between processors, providing a scalable solution across Freescale’s multicore offerings. The new processor combines control, datapath and application layer processing, and is well suited for wireless infrastructure, enterprise routing and switching and industrial applications.

The P4040 is manufactured using 45-nm process technology and features dual memory controllers and the same advanced caching, interconnect acceleration and high-speed I/O technologies as the P4080 processor. The P4040 also leverages the P4080’s embedded hypervisor and Datapath Acceleration Architecture technologies.

The new device integrates four industry-leading e500mc cores based on Power Architecture technology, delivering frequencies of 1,5 GHz per core. Each core has a dedicated 128 KB L2 backside cache and access to 2 MB of shared frontside L3 cache. Full processor independence, including the ability to boot and reset each individual e500mc core, is a defining characteristic of the device. In addition, the P4040 boasts dual memory controllers that support DDR2 or DDR3 memories, allowing board designers to utilise the latest memory technologies.

The P4040 integrates I/O technologies including dual 10 Gbps Ethernet (XAUI) controllers and eight 1 Gbps Ethernet (SGMII) controllers for packetised data processing. For non-packetised processing, there are three PCI Express v2.0 controllers/ports running at up to 5 GHz and two Serial RapidIO controllers/ports running up to 3,125 GHz.
