Variable "RAWHLS" Definition Problem #115

Closed honggangyu closed 5 years ago

honggangyu commented 5 years ago

Hi,

Regarding the BNN-PYNQ (https://github.com/Xilinx/BNN-PYNQ), I have met one intractable problem while compiling the source code on PYNQ-Z1 board running ubuntu system.

Here is the problem related to my project and unsolved before:

When compiling the "BlackBoxJam" function in the file "BNN-PYNQ/bnn/src/library/host/foldedmv-offload.h", I find that the variable "RAWHLS" at line 134 "#if defined(OFFLOAD) && defined(RAWHLS)" need to be predefined. Could you please tell me how to define the variable "RAWHLS" so that I can compile the "BlackBoxJam" with related libraries?

Thanks a lot for all your help!

I don't think I understand the problem. Anyway, those variable are defined at compile time according to the need in the make-sw.sh script. When we compile the code using software execution (thus compiling the HLS C++ code as software), we use the -DRAWHLS (line 108) flag to compile that part of the code.

Thanks so much! :)

Hi Giulio,

Thanks for your reply! Could you please introduce the difference between the code using software execution and the code using hardware execution?

Thanks!
