Abstract: Application Specific Integrated Circuit (“ASIC”) devices, such as Field Programmable Gate Arrays (“FPGAs”), may be interconnected using serial I/O connections, such as high speed multi-gigabit serial transceiver (“MGT”) connections. For example, serial I/O connections may be employed to interconnect a pair of ASICs to create a high bandwidth, low signal count connection, and in a manner so that any given pair of multiple ASIC devices on a single circuit card may communicate with each other through no more than one serial data communication link connection step. A reconfigurable hardware architecture (“RHA”) may be configured to include a communications infrastructure that uses a high-bandwidth packet router to establish standard communications protocols between multiple interfaces and/or multiple devices that may be present on a single circuit card. Dynamically-sized data packets, sized in accordance with the amount of data ready to be sent, are transferred between the devices and/or interfaces on the card.

Abstract: A system for determining the median of a plurality of data values comprises a plurality of field programmable gate arrays (FPGA), a plurality of inter FPGA links, an input router, a plurality of median modules, and a plurality of output transfer modules. Each FPGA includes a plurality of configurable logic elements and configurable storage elements from which the other components are formed. The inter FPGA link allows communication from one FPGA to another. The input router receives the plurality of data values and creates a plurality of data streams. The median module receives at least one data stream, increments a plurality of counters corresponding to a single data value within the range of data values, and determines the median by accumulating the contents of each counter. The output transfer module transfers the median to an external destination along with performance statistics of the determination of the median.

The FPGA may include a plurality of configurable logic elements and a plurality of configurable storage elements. The lookup table may be accessible by the FPGA and may store a plurality of correction components associated with each pixel, including a gain value, an offset value, and a bad pixel value. The correction module may be formed from the configurable logic elements and configurable storage elements and may receive the characteristic data and the correction components. The correction module may generate corrected data for each characteristic data by utilizing the gain value, the offset value, and the bad pixel value.

Abstract: A system and method for storing and retrieving a sparse matrix from memory of a computing device while minimizing the amount of data stored and costly jumps in memory. The computing device may be an FPGA having memory and processing elements. The method comprises storing non-zero data elements of the matrix in a data array and storing their corresponding column address values in a column index array. To read this stored data from memory, each preceding value of the column index array may be compared with each current value of the column index array to determine if the data array value corresponding with the current column index array value belongs on the next row of the matrix. The method may include pre-ordering the matrix with zero-pad placeholders or creating a row increment pointer array which typically stores fewer values than the number of rows in the matrix.
