In this paper, low-cost concurrent error detection (CED) schemes for logarithmic converters are proposed. By adopting our previously proposed logarithmic converters with developed converters with the same functions, the proposed schemes can perform logarithmic conversion with CED ability. Simulation results show that our proposed CED schemes for logarithmic converters can achieve at most 61.65% area...
Shift-add/subtract circuits constitute the basic building blocks of several frequently used complex arithmetic units such as multiple constant multipliers, exponentiation circuits, fast division circuits, CORDIC rotators, logarithmic and residue number conversation units, etc. Fine-grained pipelined designs of these arithmetic units have strong potential to improve the power-performance-reliability...
