LONDON – Fabless networking chip firm Cavium Inc. (San Jose, Calif.) has announced that it is planning to deliver a family of multicore system-chips based on full custom cores designed to implement the 64-bit ARMv8 instruction set architecture from ARM Holdings plc (Cambridge, England), The chips will be aimed at "cloud" and data center opportunities, the company said.
The so-called Project Thunder processors will be offered alongside Octeon and Nitrox processor families. Octeon processors are based on core licenses from MIPS Technologies Inc. (Sunnyvale, Calif.). Cavium said it has chosen to use MIPS or ARM architectures based upon the target end market, industry trends, installed software base, ecosystem and customer demand.
Project Thunder will provide a scalable family of 64-bit ARMv8 processors incorporated into an SoC architecture that includes workload accelerators and industry standard I/O ports. The company did not indicate how many cores it is expects family members to include or how soon they would be available in the market. Cavium did say it would announce details at a later date.
Cavium is aiming to provide a 10 times improvement in the price, performance and power over rivals' alternatives for the target applications.
The ARMv8 architecture from processor IP licensor ARM is the first to include 64-bit execution.
ARM has tipped two ARMv8 cores that are being designed for implementation in 20-nm silicon and expected to come to market in 2014. These are codenamed Atlas and Apollo (see ARM tips gods and heroes roadmap).
"Cavium is a leading multicore processor vendor and has delivered highly differentiated SoCs including a range of ARM processor-based products for many years," said Warren East, CEO of ARM, in a statement.
In the same statement Syed Ali, CEO of Cavium, said: "The adoption of the ARMv8 architecture combined with ARM's extensive software ecosystem will enable us to extend the reach of our innovative, high performance multicore SoCs to new customers and applications."
So much for MIPS! What is curious is that Cavium decided to license the architecture and implement its own cores - similar to AppliedMicro's X-Gene, although APM has a few years head start on them. This can only be good for the ARM camp with another david arming itself against the Intel goliath.
I wonder if cavium is going to stick to its tried and tested sea of wimpy cores like the octeon or will they try to target higher performance.
Pretty good move on ARM's behalf. After 4 years of touting their Quadcore-A9 they realized that it simply does not cut it for Server Applications. A9 will always be memory limited since it is a 32-bit CPU.
The question remains: Did they really miss the boat of 64-bit since the train has left the station!!
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
