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 and 32% delay reductions. Our proposed low-cost CED schemes can be applied to real-time computation-intensive computations for achieving high-speed logarithmic conversions with CED ability.

In this paper, new recoding methods for fully pipelined parallel CORDIC (COordinate Rotation DIgital Computer) are proposed. By employing new proposed MAR (Micro-rotation to Angle Recoding), fully pipelined parallel CORDIC rotation schemes can be obtained so that they can reduce the bottleneck of conventional parallel CORDIC rotators which have two separate micro-rotation stages. Although our proposed methods would produce more micro-ration stages compared with previous methods, these stages can be further merged to save area costs and to enhance the overall performance of CORDIC rotations. Our proposed methods can be applied to sine/ cosine generators, DDFS (Direct Digital Frequency Synthesizer) and other related applications for fast computations.
