BittWare Inc., a supplier of hybrid (DSP and FPGA) board-level solutions based on Analog Devices' TigerSHARC and Altera's FPGA technology, announced the release of ATLANTiS Rev 2.0 (Advanced Transfer Link Architecture for New TigerSHARC), an I/O switching and processing device.

ATLANTiS, implemented in the FPGA on each of BittWare's TS201 (T2) family boards, facilitates off-board I/O and provides communications routing and processing, allowing system designers to setup and dynamically change connections as their specific applications require. All inputs and outputs are routed through ATLANTiS, supporting a throughput of greater than 5GBps per cluster. By tightly integrating the DSPs, PCI bridge, PMC interface and I/O peripherals with the on-board FPGA, explained BittWare, ATLANTiS gives designers nearly infinite options for configuring and routing the I/O, greatly increasing the performance and flexibility of multi-processor, multi-board applications.

"Our TS201 boards have an incredible amount of I/O bandwidth available via link ports, digital IO and high-speed serial transceivers. By routing data between any and all of these, while allowing the customer to easily add FPGA processing at any place in the data flow, ATLANTiS greatly simplifies system implementation and integration," said Jeffry Milrod, President and CEO of BittWare.

Each T2 cluster consists of four TigerSHARC processors and one ATLANTiS FPGA. The eight bi-directional TigerSHARC link ports routed to the ATLANTiS FPGA provide 2GBps of data transfer between the DSPs and ATLANTiS. Using its eight SerDes high-speed serial transceiver channels and its digital I/O blocks, each ATLANTiS can communicate off-board at greater than 5GBps; boards containing two ATLANTiS clusters can provide greater than 10GBps. ATLANTiS can be configured to connect any I/O or link port to any other I/O or link port, allowing any combination of inputs and outputs to be routed together; broadcast, multicast and dynamic reconfigurability are also supported. The digital I/O blocks, including PMC+ and high performance off-board connectors, can be individually configured as single-ended or LVDS. ATLANTiS also allows designers to route data to internal FPGA processing blocks for pre-, post- or co-processing.
