HLS : create several clock

Hi,

 

I am designing video processing algorithm with vivado HLS.

 

I wanted to know if it is possible to create several clocks, i mean if the algorithm clock can be different from the AXI clock ?

Also how to do it because i did not found it in the documentation.

 

Thanks.

 

Ugo

Re: HLS : create several clock

Multiple clocks are only supported in SystemC designs.  Each SC_MODULE is synthesized using a single clock.

If you are using SystemC, you should be able to know how to do it.

Re: HLS : create several clock

Just wanted to add to Bruce's reply: we include a SystemC multi-clock example in Vivado HLS installation. It is in the directory below:

 

C:\Xilinx\Vivado_HLS\2013.2\examples\coding\sc_multi_clock

 

Cheers,
Jim
