Integrated Device Technology, Inc. (IDT - NASDAQ: IDTI), a supplier of mixed-signal semiconductor platforms, announced that Curtiss-Wright Controls Embedded Computing (NYSE: CW) has selected multiple devices from IDT’s PCI Express (PCIe) and Serial RapidIO portfolios for use on its CHAMP-AV5 and CHAMP-AV8 digital signal processing (DSP) solutions.
By leveraging the features of IDT’s PCIe and RapidIO products, Curtiss-Wright says the CHAMP-AV5 and CHAMP-AV8 DSPs will leverage the floating-point performance of the Intel Core i7 architecture to high-performance digital signal processing computing solutions tailored for defense applications such as radar, sonar, signal intelligence and image processing.
The CHAMP-AV5 multi-processing board utilizes a pair of 2.53GHz dual-core Core i7 processors in a VME64x form factor standard. The processors are connected using the IDT 89HPES32NT8BG2, a 32-lane, 8-port PCI Express Gen 2 switch designed to support multiprocessor designs through unique features including dual Direct Memory Access (DMA) functions, multiple clock domain isolation, and an unprecedented eight non-transparent bridging (NTB) functions to enable root complex isolation, failover support, and inter-processor communication between PCIe domains.
Supporting Gen2 Serial RapidIO and PCIe interfaces, Curtiss-Wright says the CHAMP-AV8 OpenVPX multi-processing board offers triple the bandwidth of first generation VPX products with up to 32 GB/s of fabric performance to complement the additional processing performance supplied by two quad core Intel Core i7 processors.
Key to the enablement of RapidIO with Intel PCIe based processors is the IDT Tsi721 PCIe Gen 2 to RapidIO Gen 2 protocol conversion bridge. The Tsi721 translates a 16 Gbps port of the PCIe protocol to RapidIO and vice versa. An IDT CPS-1432 provides RapidIO Gen 2 switching and connection to an offboard interface at up to 20 Gbps per port for multiprocessing expansion. An IDT 89HPES32NT8BG2 PCI Express Gen 2 switch is used for connection of the processors to an offboard expansion interface as well as an onboard XMC card connector.
“In multiprocessor environments, the use of key functionality such as NTB and DMA are essential in utilizing PCIe as an interconnect fabric," explains Lynn Bamford, vice president and general manager of Curtiss-Wright Controls Embedded Computing. "For applications that use RapidIO as the primary interconnect, the Tsi721 allows the use of x86 processors based on PCIe while still taking advantage of the compelling features of RapidIO.”
