Accumulators in AIE API rely on the aie::accum class template. More...
Overview
Accumulators in AIE API rely on the aie::accum class template.
The first argument of this template is an element type tag that specifies the accumulation class (integer, complex, floating point, ...) and the required accumulation bits.
