1/23/2003 - Synergy Microsystems, Inc. (Synergy) announced the introduction of a powerful new VME-based, single board computer (SBC) platform that is the first to integrate StarFabric, a high-speed, point-to-point switched backplane and chassis-to-chassis interconnect solution.

The high-bandwidth switching fabric has been integrated into Synergy’s new Raptor DX SBC ­ the first of a new family of VME-based SBCs controlled by the Power PC 7455 processor. Driven by this most advanced of the G4 series CPUs, the Raptor DX delivers clock speeds up to 1 GHz, with a roadmap to even higher speeds.

"The embedded industry continues to push performance limits," noted Thomas Powell, Synergy CEO, "with faster processors, higher speed memory and more demanding I/O rates. We’re delighted to be the first to integrate a next-generation, higher speed network that keeps pace with the faster clock times and greater throughput our clients are requesting," he noted. "With a StarFabric aggregate throughput roughly four to five times that of Gigabit Ethernet, and extremely low latency for short transfers, we believe this unprecedented combination of switching and CPU power gives the market the best overall performance in a single-slot VME solution."

Available in single or dual processor configurations, each Raptor CPU is supported by three levels of enhanced cache memory, for a dramatic speed and efficiency gain over the earlier 7410 series boards. In the new boards, the 256-KB L2 cache joins the 64-KB L1 on-chip. Now integrated with the CPU core, the L2 can operate at speeds approaching the frequency of the processor. Its eight-way associativity provides better system coverage ­ locating data faster and more efficiently. Enhanced by Dual Data Rate cache, the 2 MB, backside L3 cache achieves a data throughput of 532 MHz.

StarFabric connectivity on the Raptor DX is achieved through the on-board StarGen SG 2010 bridge chip, which provides two 2.5 Gbps, full-duplex StarFabric interfaces. This bridge translates PCI traffic into serial frame format for transmission across a StarFabric network, and supports both 32- and 64-bit PCI buses running either 33 or 66 MHz. By connecting multiple bridges, the highly scalable StarFabric architecture allows engineers to design custom data network topologies with unprecedented board-to-board communication capability.

The Raptor DX provides additional capability to the 7455 processor with the Marvel DiscoveryTM advanced system/memory controller -- a single chip that integrates fast memory, dual 64-bit/66 MHz PCI buses and abundant I/O functionality, all routed through a high-bandwidth internal crossbar fabric.
