Multi-core, multithreaded processors gain Linux support

Aug 7, 2007 — by LinuxDevices Staff — from the LinuxDevices Archive — 8 views

Raza Microelectronics Inc. (RMI) announced that two of its multi-core, multi-threaded MIPS-based processor families are now supported by Wind River's Carrier Grade Linux distribution. Wind River's Platform for Network Equipment, Linux Edition (PNE-LE) includes multi-threaded debugging capabilities that speed development on RMIs XLR and XLS chip families, the companies claim.

RMI describes its SPS XLR and XLS chips as general-purpose processors for communications, networking, wireless, and security applications. XLR family chips integrate four or eight MIPS64 cores clocked up to 1.5GHz. Each core is said to implement fine-grained, four-way multi-threading, for the equivalent performance of 16 or 32 separate cores. The XLS family is a cost-optimized version of the XLR.

Wind River's Platform for Network Equipment, Linux Edition is a Carrier Grade Linux (CGL) distribution said to be well-suited for developing control and management system software in 3G wireless infrastructure systems and IMS, WiMAX elements, fixed-mobile convergence (FMC) elements, soft switches, media gateways, and multi-service switches. The distribution includes Workbench development tools, which in April gained new multi-threaded debugging capabilities.

Vincent Rerolle, VP of corporate strategy at Wind River, stated, “We are offering customers a wholly integrated multi-core networking development option.”

No pricing or availability details were disclosed.
