■ The FAB-3226 Digital Bit Pattern Generator connects digital ports to an user-defined FPGA logic. As the FPGA is user-programmable all kind of operation can be implemented: input, output, and closed loop operation where input and output are processed in real-time. All this can be controlled by an user-defined application program running on a computer system (PC or embedded).

Overview
The FAB-3226 system connects 16 bi-directional I/O ports to an user-defined FPGA logic. As the FPGA is user-programmable all kind of operation can be implemented: input, output, and closed loop operation where input and output are processed in real-time. All this can be controlled by an user-defined application program running on a computer system (PC or embedded).
Due to the flexible architecture of the FAB-3226 a broad range of functions can be implemented: digital stimuli, digital data capture, closed-loop processing, random bit-pattern generators, serial/parallel data communication interfaces, synchronous or asynchronous operation.
In order to communicate with the application, the logic may implement a set of registers. The application exchanges data with these registers by read and write requests. This way the application can control the logic
No firmware development is required as the FAB kit contains all the necessary drivers.
The FPGA logic is soft, i.e. the application initializes the FPGA upon each start. The FPGA is de-initialized (reset) when the application terminates. By use of an server application the FPGA logic might persist even when a single client terminates.
