Buffer memory supports serial switch fabrics

The MM-6171 is a rugged COTS product providing 2 to 4Gbyte of high speed buffer memory.

New from Vmetro, the MM-6171 is a buffer memory node in an XMC form factor with support for Serial RapidIO or PCI Express.

The MM-6171 is a rugged COTS product providing 2 to 4Gbyte of high speed buffer memory.

Primarily used in digital signal processing systems for high-speed temporary storage, expanded system memory, interleaving and data aggregation and warehousing, the MM-6171 is ideal for embedded applications such as radar signal processing, signal intelligence and image acquisition that require buffering capability with an FPGA memory controller.

"The MM-6171 leverages the company's significant experience in FPGA-based implementations of Serial RapidIO and PCI-Express", says Mike Jadon, Chief Technology Officer - Embedded Systems at Vmetro: "This product represents the first XMC buffer memory node for these serial switch fabrics, providing a method for rate buffering not previously available on this technology".

The MM-6171 includes a bus interface and DMA engine.

The Serial RapidIO x4 interface runs at 3.125GHz with a corner-turning, striding DMA engine for advanced functionality in DSP systems.

For PCI Express applications, the x8 bus interface runs at 2.5GHz and also provides a full-featured DMA engine.

"An XMC memory node with a RapidIO interconnect is a great addition to the RapidIO ecosystem", says Tom Cox, Executive Director, RapidIO Trade Association.

"Because RapidIO technology was designed as a system-level fabric specifically for the embedded market, this product will allow customers to easily add high-speed, low-latency system memory into their system wherever they have a spare XMC site".

Vmetro provides MM-6171 drivers for VxWorks 6.x and Linux 2.6.x.

The MM-6171 is available in commercial, convection-cooled and ruggedised, conduction-cooled variants.
