If you have a question about this talk, please contact Grigorios Mingas. This talk will begin with an overview of floating point arithmetic. It will introduce how errors arise from the use of a finite precision number representation and then describe the many factors which affect the size of these errors, including the input data range, the choice of precision, the compiler for a software implementation or the architecture of a hardware implementation. We will follow this with a discussion on the implications of these factors on what is a `correct’ comparison between any hardware and software implementation of an algorithm. This discussion will naturally develop into a analysis of the relationship between precision, error and architecture of a hardware accelerator. Finally, Bianca will present her initial research findings based upon manipulating the architecture of a hardware accelerator to meet a design specification, with the ultimate goal of using precision analysis tools to find `free parallelism’. This differs significantly from the more traditional work in the the field of word-length optimisation that involves tuning the precision used throughout a chosen hardware architecture.
