TigerSHARC DSP VME COTS Solutions
BittWare offers VME format COTS solutions featuring the Analog Devices
ADSP-TS201 TigerSHARC DSP, the ADSP-TS101 TigerSHARC DSP and the ADSP-21160 Hammerhead SHARC
processors.
T2-VME
The BittWare T2-6U-VME (T2V6), represents the first ever COTS VME/VXS board
based on the Analog Devices ADSP-TS201 TigerSHARC DSP. Designed for demanding multiprocessor
based military applications, and targeted at a broad range of applications including radar,
sonar, communications, and imaging, the BittWare T2V6 is available in both air-cooled and
conduction-cooled versions and now gives VME users full access to the power of the ADSP-TS201
TigerSHARC DSP, providing optimal solutions for the most demanding of applications.
To take full advantage of the high performance TigerSHARC DSP, the BittWare
T2V6 implements BittWare’s ATLANTiS (Advanced Transfer Link Architecture for New TigerSHARC)
architecture, which combines robust TigerSHARC processing with the versatile Xilinx Virtex-II
Pro FPGA to offer ultra high performance and unprecedented I/O bandwidth. The T2V6 matches the
ADSP-TS201 TigerSHARC DSPs with:
- High-bandwidth, low-latency off-board I/O, reconfigurable for nearly any application
- High-speed interprocessor communication network to facilitate scalability
- SharcFIN PCI-DSP bridge for integrating DSPs with PCI bus and other peripherals
- Comprehensive software for ease-of-use
Rugged VME COTS Solutions
Air cooled and conduction cooled versions of the BittWare
T2V6 are available. The standard options available include commercial,
Level 1u, Level 1c, Level 2c and Level 3c.
Please contact Sarsen Technology for
full details of the ruggedization levels.
The T2V6 VME/VXS board also provides two large on-board banks of SDRAM, flash
memory for hostless boot, and a PMC site for adding additional processors or I/O capabilities.
High-Performance TigerSHARC DSP Processing
The BittWare T2V6 features eight ADSP-TS201 TigerSHARC DSPs
from Analog Devices, arranged as two clusters of four. The four processors in each cluster
are interconnected by a 64-bit, 83.3 MHz cluster bus. The ADSP-TS201 processor operates at up
to 600MHz, 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 1 GB/sec each. Two link ports from
each DSP create an interprocessor communications ring, and the remaining two link ports are
routed to the ATLANTiS FPGAs (running at half-speed, 500 MB/sec each).
SharcFIN PCI-DSP Bridge
The T2V6 features two BittWare SharcFIN PCI-DSP bridge chips, one per DSP
cluster, to give the DSPs low-overhead access to the host and PMC site via the 64-bit, 66MHz
PCI interface. The SharcFIN also provides a general purpose peripheral bus that allows the
DSPs to access the Flash and the FPGA control registers. It also provides host access to the
DSPs, on-board SDRAM, Flash, and FPGA control registers.
High-Bandwidth, Low-Latency Off-Board I/O
The T2V6 boasts a tremendous amount of I/O bandwidth and
options, including sixteen LVDS link ports, one PMC site with BittWare’s
PMC+ I/O extensions, high-performance digital I/O headers, and eight RocketIO
high speed serial transceivers. Total potential I/O
bandwidth is greater than 6 GB/ sec.
Xilinx Virtex-II Pro FPGA
Two Xilinx Virtex-II Pro (XC2VP20/30Preliminary) FPGAs,
one per DSP cluster, add tremendous flexibility to the board and are useful
for routing communications, translating
protocols, and implementing algorithms. They are used to implement
eight on-board TigerSHARC link ports and support a variety of external
digital I/O (DIO), flags, and interrupts. Each
Xilinx Virtex-II Pro also provides eight RocketIO high speed serial
transceivers, which are brought off-board, for additional external communications.
ATLANTiS: A Superior Architecture for a Superior Processor
To facilitate off-board I/O and provide communications routing and
processing, the T2V6 features a dual BittWare ATLANTiS architecture, which is implemented in
the Xilinx Virtex-II Pro FPGAs. All off-board I/O for the board, which includes external link
ports and digital I/O blocks, is routed through the FPGAs, which can support a throughput of
4.6 GB/sec each. By tightly integrating the DSPs, PCI bridge, PMC interface, and I/O
peripherals with the on-board FPGAs, ATLANTiS gives designers nearly infinite options for
configuring and routing the I/O.
The eight bi-directional TigerSHARC link ports routed
to each ATLANTiS FPGA provide 4.6 GB/sec of data transfer between the
DSP cluster and the FPGA. Using its eight
RocketIO high-speed serial transceiver channels and its digital I/O
blocks, each FPGA can communicate off-board at greater than 4.8 GB/sec.
It can be configured to connect the I/Os to
each other or to the ADSP-TS201 link ports, allowing any combination
of inputs and outputs to be routed together. The digital I/O blocks include
PMC+ and high performance off-board
connectors. Each digital I/O signal can also be individually configured
as single-ended or LVDS. ATLANTiS adds tremendous flexibility to the DSP
subsystem, allowing system designers to
route the link ports and digital I/O blocks as their specific applications
require.
T2 Board Family
The T2V6 VME / VXS COTS board is part of BittWare’s T2 board family, which
features the ADSP-TS201 TigerSHARC DSP on a variety of platforms. The boards all feature a
common, scalable architecture - ATLANTiS - and are available in PCI-X plug-in, PMC, 6U VME, and
6U CompactPCI form factors.
Tiger-VME
BittWare's Tiger-VME (TSVM) COTS card features the processing power of eight
Analog Devices 250MHz ADSP-TS101 TigerSHARC DSPs. The Tiger-VME also features a 64-bit, 66MHz
PCI interface and shared memory. This memory comprises two banks of up to 256MB SDRAM each and
two banks of 8MB of Flash.
The Tiger-VME is shipped as two BittWare
TigerSHARC-PMC+ cards
mounted on a VME carrier card.
The carrier cards that can be specified include:
- Pelican from Sabtech Industries
- VME-PMC-CADDY from ESD (Electronic System Design)
