Generation of Synthetic Floating-Point benchmark circuits

Synthetic Floating-Point (SFP), a synthetic benchmark generator program for floating-point circuits is presented. SFP consists of two independent modules for characterisation and generation. The characterisation module extracts key dataflow statistics of an arbitrary software program. Generation involves producing randomised circuits with desired statistics which are either the output of the characterisation module or directly generated by the user. Using the basic linear algebra subprograms (BLAS) library, Whetstone benchmark and LINPACK benchmark, it is demonstrated that SFP can be used to generate floating-point benchmarks with different user-specified properties as well as benchmarks that mimic real computational programs.
