ABSTRACT:
A field programmable gate array is configured to interface a source of externally produced input digital signals to a host computer system. The input signals having a first data type are reformatted to output digital signals having a second data type compatible with the computer system. The computer system can be used for storing and processing the output digital signals. The interface includes a first set of registers connected to the external source. The first set of registers store first portions of the input digital signals. A first buffer connected to the first set of registers store a combination of the first portions of the input digital signals, the combination of the first portions of the input digital signals stored in the first buffer formatted according to the second data type. The interface also includes a direct memory access controller to transport the combinations of the first portions of the input digital signals as output digital signals to the memory of the computer system.
