BittWare GT-3U-cPCI Ruggedized Hybrid Signal Processing 3U CompactPCI Board

BittWare's GT-3U-cPCI (GT3U) is a ruggedized 3U CompactPCI board that has been designed for demanding multi-processor based applications requiring complete flexibility and adaptability. The GT3U features a large Altera Stratix II FPGA and one cluster of four Analog Devices ADSP-TS201S TigerSHARC (ADSP-TS201)processors. The GT-3U-cPCI also features a front panel interface supplying four channels of high-speed SerDes tranceivers and a back panel interface providing RS232/ RS422 and 10/100 Ethernet.

ATLANTiS Architecture

Simultaneous on-board and off-board data transfers can be achieved at a rate of 4 GB/s via BittWare’s ATLANTiS architecture implemented in the Stratix II GX. The board also provides a large amount of on-board memory including 1 GB of DDR2 SDRAM or 64 MB of QDR SDRAM, as well as 64 MB of flash memory for booting the FPGA and DSPs.

Altera Stratix II GX FPGA

At the heart of the BittWare GT3U is a state-of-the-art Altera Stratix II GX FPGA containing 90,960 equivalent LEs, 4.5 Mbits of RAM, 192 embedded 18x18 multipliers, 48 DSP blocks, and 8 PLLs. The Altera FPGA provides pre-, post-, or co-processing to complement the Analog Devices TigerSHARC processing cluster, while also enabling seamless routing of the TigerSHARC I/O at a rate of over 2 GB/s via BittWare’s ATLANTiS architecture.

Analog Devices ADSP-TS201 TigerSHARC DSP

The GT3U features a single cluster of four Analog Devices ADSP-TS201S TigerSHARC DSPs, which are interconnected by a 64-bit cluster bus running at up to 100 MHz. The ADSP-TS201 processor operates at up to 600 MHz, providing 3.6 GFLOPS of peak processing power. Because of its superscalar architecture, the ADSP-TS201 is also efficient at fixed-point processing, with each DSP supporting 14.4 BOPS of processing. Along with 24 Mbits of on-chip RAM, each DSP also boasts four high-speed LVDS link ports running at up to 500 MB/s each. Two link ports from each DSP create an interprocessor communications ring, and the remaining two link ports are routed to the on-board FPGA.

SharcFINe PCI-DSP Bridge

The GT3U features a BittWare SharcFINe PCI-DSP bridge chip that gives the DSPs low-overhead access to the host via the 32-bit, 66 MHz PCI interface. The SharcFINe also provides a general purpose peripheral bus that allows the DSPs to access the Flash, the 10/100 Ethernet, and the RS232/RS422 UART interface. It also provides host access to the DSPs, Flash, and FPGA control registers.
