Freescale launches a 50Gbits/s network chip

Meeting the demands of downloaders

CHIP DESIGNER Freescale Semiconductor has shown off its QorIQ Advanced Multiprocessing (AMP) chips that it claims will handle the growth in internet traffic over the coming years.

Freescale's QorIQ AMP chips are based on 64-bit Power e6500 cores running at up to 2.5GHz with Altivec units. The chips will be fabricated on a 28nm process node, offer up to 24 virtual cores and are being pitched for use in switches and routers.

Three versions of Freescale's QorIQ AMP chips will be available with six core and eight core versions running at 2.5GHz and 1.6GHz, respectively. The high-end, 24 virtual core chip has 12 dual-threaded cores giving 24 threads running at 2.0GHz.

Freescale is promoting the advantages of dual threading its cores, claiming that yields improved performance per thread and higher frequencies. The chip will appear in Freescale's T4240 device and the company claims it can forward 50Gbits/s.

Chips like Freescale's QorIQ AMP designs are vital in order for networks to be able to forward data without introducing significant delays. The problem is complicated by having protocols such as IPSec and SSL, which require more than just simple IP packet forwarding.

Just about every network vendor has been banging on about how data usage will explode in the coming years, however it's not just a matter of buying more switches and routers to solve the problem but rather increasing the performance of the network fabric in order to deal with the demand.

Freescale says its QorIQ T4240 device will be shipping in early 2012, with more of its AMP devices set to tip up each quarter after the initial launch. µ
