Description

The AOS PCI-104-4000 is a high bandwidth computing platform with the resources required for today’s most complex data processing algorithm execution. Incorporating four bands of SRAM memory, this card supports highly parallelized algorithms such as those required for image processing, radar processing and neural network engines. A large reconfigurable Xilinx Field Programmable Gate Array (FPGA) onboard the PCI- 104-4000 provides the user with the computational power for applications where a traditional CPU will not get the job done.

Operation

The AOS PCI-104-4000 utilizes Xilinx Virtex-4 (LX series) FPGA technology. Users can select between three different Virtex-4 LX types (100, 160, 200) depending on the resources required for the application. The LX-200 provides the largest amount of resources to the user in the Virtex family. The PCI-104-4000 also provides a high speed auxiliary bus to allow processed data to be transferred to, or received from, another board (such as the AOS PCI-104-3000) without using the system PCI bus. The high speed auxiliary bus can support a user designed daughter card for interfaces based on the desired sensor input. The four banks of fast memory with a direct interface to the FPGA make the PCI-104-4000 perform image processing and neural network applications where large data sets need to be temporarily stored.

AOS Real-World Application

In 2009, AOS developed a hardware system designed to process camera data in real-time for six-degree-of-freedom (6DOF) state information. The application was autonomously docking a spacecraft to the International Space Station (ISS). The system AOS developed utilized both the PCI-104-3000 and the PCI- 104-4000. The system was tested in a space simulation facility and demonstrated the ability to provide navigational information required for docking to the ISS.
