One advantage of Arm's new interconnect is that it will be able to connect a wide range of elements that may go into an SOC, including DSPs (digital signal processors) and specialized functions developed by individual network equipment vendors, Sonnier said. Arm plans to license the interconnect, so makers of different components will be able to use interfaces that talk to it, he said. Licensing should make the CCN-504 more attractive to system makers, Sonnier said.
In addition to networks, the new interconnect can also be used in storage and in servers, where Arm sees a particular need for it in distributed data centers designed to serve applications at high speed from sites closer to users, Forsyth said. Arm's other lead partner for the CCN-504 is server silicon vendor Calxeda.
Arm's new memory controller, the CoreLink DMC-520, is designed for faster and more efficient access to internal cache and external memory, saving both time and energy, Forsyth said. It can be used in conjunction with the CCN-504 and is expected in the same time frame.
