implement two different systems (one with floating point library and one without), then compare their output results to each others

Hello,

i want to have two system (for example, CPU 1 and CPU 2) doing the same calculation process. One of them working with floating-point arithmetic and other without floating piont arithmetic. The idea then is to do a comparaison between the two systems regarding the precision of calculations in each systems (results of both systems). 

Or for example, implement a vhld block (multiplication function) in cyclone V through NIOS or ds-5 debugger. The ARM core working of course with floating point library, and execute in parallel same operations (multiplication function). At the end, both results need to be compared in some way. Is it possible to do this kind of implemetation and what are the possible ways?

Thanks in advance.

Hi,

From my understanding, you need to implement two systems ate the same time and compare them. So you can follow the multi core example that shows you how to have two or more isolated NIOS systems running at the same time on one FPGA.

The following links shows the available design examples and the HOW-TO videos:
