\u3ci\u3eMcphersonarcys\u3c/i\u3e, a New Genus for \u3ci\u3ePentatoma Aequalis\u3c/i\u3e Say (Heteroptera: Pentatomidae)

A new monotypic genus, Mcphersonarcys is erected to hold Pentatoma aequalis Say, a species formerly placed in the genus Hymenarcys. Based on the distribution of 19 character-states Hymenarcys forms a clade with its sister genus Coenus. Both genera are related to the large genus Euschistus. Mcphersonarcys is basal to Euschistus, whereas the clade with Hymenarcys and Coenus is derived. Removal of P. aequalis to a new genus resolves the paraphyly of Hymenarcys sensu lato

Generic and Universal Parallel Matrix Summation with a Flexible Compression Goal for Xilinx FPGAs

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 and in the context of concrete applications or specific implementation technologies. This paper is building on this history and describes a generic implementation of a bit matrix compressor for Xilinx FPGAs, which does not require a generator tool. It contributes FPGA-oriented metrics for the evaluation of elementary parallel bit counters, a systematic analysis and partial decomposition of previously proposed counters and a fully implemented construction heuristic with a flexible compression target matching the device capabilities. The generic implementation is agnostic of the aspect ratio of the input matrix and can be used for multiplication the same way as it can be for single-column population count operations
