摘要: On line arithmetic is a computation tool able to adapt the precision expected by user. Developing library of on operators for FPGAs will lead in near future spread brick-assembled application-dedicated operators. In implementation basic operations (addition, multiplication, division and square root), we have met some new problems: our work has involved changes VLSI design methodology order achieve effective performances. We shall present modified on-line algorithms their adaptation cell oriented FPGA architecture. The correct integration retiming barriers proved be critical as far speed concerned.
