Bit matrix compression is a highly relevant operation in computer arithmetic. Essentially being a multi-operand addition, it is the key operation behind fast multiplication and many higher-level operations such as multiply-accumulate, the computation of the dot product or the implementation of FIR filters. Compressor implementations have been constantly evolving for greater efficiency both in general...
The binary word addition was one of the earliest operations that called for special-purpose hardware structures on otherwise freely programmable logic devices. The large logic depth induced by the great fanin that comprises both operands of the addition is especially harmful in SRAM-programmed FPGAs where the delays of the configurable inter-LUT routing are expensive in comparison to the delays of...
Standard libraries and frameworks boost the productivity and performance significantly as they enable the re-use of optimized solutions for standard tasks. Hardware designs are often unnecessarily complex because a) a rich RTL library of standard solutions is missing and b) designs must often sacrifice portable and readable behavioral descriptions so as to meet timing and area constraints on the targeted...
The mapping of reads, i.e. short DNA base pair strings, to large genome databases has become a critical operation for genetic analysis and diagnosis. The underlying alignment operation essentially is a string search tolerating some character mismatches and possibly character deletions or insertions with respect to a reference genome. Its output comprises the locations within the reference that are...
Field-Programmable Gate Arrays, which are widely used as prototyping platforms, are intruding the domain of custom-specific high-performance hardware accelerators, which operate highly efficiently by exploiting bit- and word-level parallelism. One opportunity to feed these FPGA accelerators with Gbytes of data is the direct attachment of mass-storage devices through a Serial-ATA link. State-of-the-art...
