Abstract
We have implemented customized SIMD 16-bit floating point instructions on a NIOS II processor. On several image processing and media benchmarks for which the accuracy and dynamic range of this format is sufficient, a speed-up ranging from 1.5 to more than 2 is obtained versus the integer implementation. The hardware overhead remains limited and is compatible with the capacities of today's FPGAs.
