SAN FRANCISCO Raza Microelectronics Inc. has added a lower-cost multicore, multithreaded processor to its Scalable Processor Solutions line of control/data-plane devices. The XLS family is positioned and priced below the company's existing XLR family, using a 90-nanometer process to offer eight-core MIPS processors with frequencies between 800 MHz and 1.2 GHz.
The RSA Conference here was a good venue for the chip family's launch, said Lance Smith, vice president and general manager of RMI's information infrastructure solutions group, since RMI aims to enable hardware firewalls and unified threat management systems at sub-$5,000 prices. The processors are expected to find a particular home in open designs based on the Advanced Telecommunications Computing Architecture, he said.
Like the XLR, the XLS family relies on MIPS64 cores, with each of the dual CPU cores offering four threads per core. While the XLR family can scale to eight cores instead of two, few compromises were made in actual processing performance in moving from the XLR to the XLS, Smith said. Instead, the processors were designed with smaller footprints and space-constrained layouts, and were designed for low-power systems with typical dissipation scaling between 10 watts and 49 W.
The XLS family comprises three processors with different scaling: the XLS200, 400 and 600.
