这款VME64x Altivec引擎代表了Curtiss-Wright广泛的设计和平台专业知识，为VME COTS系统的高性能信号处理树立了新标准。”6U VME64x CHAMP-AV IV以高达40 GFLOPs的峰值计算能力驱动要求苛刻的DSP应用。该板的四个处理节点均由一个1.25 GHz 7447A/7448处理器、高达512 MB DDR-250 SDRAM(2GB/秒)和两个100 MHz 64位PCI-X接口组成。这款基于AltiVec的DSP引擎还采用了Curtiss-Wright业界领先的QuadFlow架构。

为了提供最大的多处理应用性能，主板的QuadFlow架构支持四个同步的节点到节点传输，以提供32GB/秒峰值。四个节点中的每一个都以最高1.6 GB/秒的峰值速度向相邻节点传输数据。CHAMP-AV IV的每个处理节点都配备了千兆以太网连接。CHAMP-AV IV上的系统扩展由两个兼容PCI-X接口的PMC站点支持。

每个扩展站点都支持最新的PCI-X规范，支持64位/100MHz操作，同时保持与传统33MHz和66MHz PMC模块的兼容性。CHAMP-AV IV高达1.6 Gbyte秒的峰值I/O带宽提供了与其四核1.25 GHz 7447A/7448处理器的DSP处理能力相匹配的吞吐量。Champ-AV IV上的两个PMC站点都支持背板连接器的低压差分信号(LVDS ),以支持使用高速串行交换互连技术，如Curtiss-Wright基于StarFabric的StarLink PMC和光纤通道PMC模块。该板提供了到背板的高速连接，从而消除了对前面板线束的需求，并提高了系统的可维护性。软件支持CHAMP-AV IV由Curtiss-Wright公司的处理器间通信库(IPC)支持

"The VME64x Altivec engine represents Curtiss-Wright's extensive design and platform expertise and sets a new standard for high-performance signal processing for VME COTS systems." The 6U VME64x CHAMP-AV IV drives demanding DSP applications with up to 40 GFLOPs of peak computing power. Each of the board's four processing nodes consists of a 1.25GHz 7447A/7448 processor, up to 512 MB DDR-250 SDRAM(2GB/ SEC), and two 100 MHz 64-bit PCI-X interfaces. The AltiveC-based DSP engine also features Curtiss-Wright's industry-leading QuadFlow architecture.

To provide maximum multiprocessing application performance, the motherboard's QuadFlow architecture supports four simultaneous node-to-node transfers to deliver 32GB/ SEC peaks. Each of the four nodes transmits data to adjacent nodes at peak speeds of up to 1.6 GB/ s. Every processing node of the CHAMP-AV IV is equipped with Gigabit Ethernet connectivity. System extensions on CHAMP-AV IV are supported by two PMC sites compatible with PCI-X interfaces.

Each extension site supports the latest PCI-X specification and supports 64-bit /100MHz operation while maintaining compatibility with traditional 33MHz and 66MHz PMC modules. The CHAMP-AV IV's peak I/O bandwidth of up to 1.6 Gbyte seconds delivers throughput that matches the DSP processing power of its quad-core 1.25GHz 7447A/7448 processor. Both PMC sites on Champ-AV IV support low-voltage differential signals (LVDS) for backplane connectors to support the use of high-speed serial switch interconnect technologies such as Curtiss-Wright's StarFabric-based StarLink PMC and Fibre Channel PMC modules. The board provides a high-speed connection to the backplane, eliminating the need for front panel wiring harnesses and improving the maintainability of the system.
