Theses and Dissertations
The set-wise summation operation is perhaps one of the most fundamental and widely used operations in scientific applications. In these applications, maintaining the accuracy of the summation is also important as floating point operations have inherent errors associated with them. Designing floating-point accumulators presents a unique set of challenges: double-precision addition is usually deeply pipelined and without special micro-architectural or data scheduling techniques, the data hazard that exists. There have been several efforts to design floating point accumulators and accurate summation architecture using different algorithms on FPGAs but these problems have been dealt with separately. In this dissertation, we present …
