PowerPC PrPMC module runs SMP Linux

Feb 28, 2006 — by LinuxDevices Staff — from the LinuxDevices Archive

Extreme Engineering Solutions is shipping a PrPMC (Processor PMC) module targeting HPC (high-performance computing) and telecom applications. The XPedite6200 module is available with dual Freescale MPC7448 processors, and up to four modules can be installed in a single AdvancedTCA slot, the company says. It supports Linux.

The XPedite6200 is available with a single MPC7448 processor clocked at 1.4GHz, or with dual MPC7448's clocked at 1.267GHz. The board can also accommodate the older, pin-compatible MPC7447A Freescale processor, known as the “G4” in Apple marketing nomenclature.

According to Extreme, several AdvancedTCA carrier cards are available that are capable of hosting up to four XPedite6200s, for a total of up to eight MPC7448 processors per slot — that's a spicy number-crunching meatball.

Another touted feature is a Bellcore 1089 surge-protected front panel Gigabit Ethernet port, useful for development or port usage in the field, the company says. PTMC configuration five ethernet ports can also be routed to J14 baseboard connectors.

Other features and specs include:

  • Marvell Discovery III MV64460 system controller, claimed to have “superior DDR memory performance”
  • 1 GB of DDR SDRAM
  • 128 MB flash
  • PCI-X

VP of sales, Bret Farnum, states, “Several early adopters have increased their system performance by an order of magnitude. And, a seemingly insignificant option like a front panel Ethernet port is a tremendous 'in-field service' advantage.”


The XPedite6200 is available from stock, priced from $3,500 in single quantities to about $2,000 in OEM quantities. Custom configurations, such as MPC7447A processors, can also be ordered.

Extreme supports Linux or QNX on the board, and also offers VxMP. The company guarantees four hour response times to technical questions, it says.

The company was founded in 2002, and is led by CEO Rob Scidmore, who previously founded embedded software specialist SciTech after nearly ten years with telecom equipment vendor Artesyn. Scidmore also runs an engineer mentor program at the University of Wisconsin in Madison.

Artesyn, meanwhile, has also introduced an MPC7448-based prPMC card that runs Linux and has a front-panel Ethernet port. Its PmPPC7448 features a single MPC7448 processor clocked at 1.7GHz, up to two Gbytes of RAM, and 64 Mbytes of Flash. Artsyn's module supports a Carrier Grade Linux OS from Wind River.
