6U VME/VXS Octal Tiger Sharc Board
The CORNET’s 6U VME/VXS Octal Tiger SHARC DSP Board (CTI07D04) offers a commercial-off-the-shelf (COTS) digital signal processing solution for system designers. It is ideally suitable for computation demanding field-based signal intelligence (SIGINT) or image intelligence (IMINT) processing applications that requires real-time processing of digitized data.
With two separate buses for computing and communications, the CTI07D04 architecture significantly reduces the bottleneck caused by extensive multitasking and interrupts found in other general-purpose multiprocessing computer architectures.
The computing (Tiger SHARC) bus has eight Analog Devices ADSP-TS201 Tiger SHARC Digital Signal Processors (DSPs). Each DSP runs at a core clock frequency of 500 MHz with a performance of 3.6 GFLOPS for floating-point operations. It has 24 Mbit onchips DRAM. It also has 14 DMA channels for blocked data transfer among the link ports and the bus. 128 MB of SDRAM and 128MB of programmable FLASH are connected in this computing bus.
The DSPs are connected via the 4-bit LVDS link ports, accessible via the VXS/VITA-41 connector on the back plane.
The communication bus (BF561 bus) includes an Analog Devices ADSP-BF561 Blackfin Processor for handling communications among processed data. The Blackfin processor runs at 500 MHz. This bus has 128 MB of SDRAM, 64 MB of programmable FLASH and 1 Mb of SDRAM.
CTI07D04 provides two 10/100/1000Base-T Ethernet ports, a USB 2.0 port, a PMC I/O expansion slot , Two 3mm Audio Jack and VME bus interface for external communication.
