LogiCORE IP Image Statistics v1.0 - Why do the POW and SUM outputs toggle when DATA_VALID is asserted?

描述

Why do the POW and SUM outputs toggle when DATA_VALID is asserted?

解决方案

This is a known issue in Image Statistics v1.0 that has been resolved in v2.0.

This can be worked around in Image Statistics v1.0 by incrementing the address and reading the output values on consecutive clock cycles.
