This paper discusses the relationship between computer arithmetic and hardware implementation. First, we examine the impact of computer arithmetic on the overall performance of today's microprocessors. By comparing their evolution over the last Barbour Vente Par Correspondance 10 years, Barbour Femme we show that the performance of arithmetic operators is far less critical than the performance of the memory hierarchy or the branch predictors. We then discuss the potential for improvement in arithmetic performance, both for pipelined and non-pipelined operations. We then examine the possible impact of new technologies, such as MMX technology or asynchronous control of microprocessors, on computer arithmetic. Finally, we show that programmable logic devices now permit a cost-effective implementation of specific arithmetic Barbour Soldes number representations, such as serial arithmetic or logarithmic representations.

Post-translational glycosylation is a universal modification of proteins in eukarya, archaea and bacteria. Two recent publications describe the first confirmed report of a bacterial N-linked glycosylation pathway in the human gastrointestinal pathogen Campylobacter jejuni. In addition, an O-linked glycosylation pathway has been identified and characterized in C. jejuni and the related species Campylobacter coli. Both pathways have similarity to the respective N- and O-linked glycosylation processes in eukaryotes. In bacteria, homologues of the genes in both pathways are found in other organisms, the complex glycans linked to the glycoproteins share common biosynthetic precursors and these modifications could play similar biological roles. Thus, Campylobacter provides a unique model system for the elucidation and exploitation of glycoprotein biosynthesis.
