Build hardware for zc702

[saraballeri]

Hi, I try to build hardware for zc702 platform with DIET_CHAI_Z using then only the convolution accelerator. I would use CHaiDNN on Pynq-Z1. Anyway, I got this error:

Is there a particular configuration, of weights or other, that allows me to synthesize and implement at least the convolution accelerator on this Zynq device?

Thanks, Sara

[saraballeri]

Hi, can anyone help me?

Thanks, Sara

[VishalX]

@saraballeri,

The current version of CHaiDNN doesn't have support for zc702 device as it has fewer resources.

We are going to make a release soon with the support for Zynq702 device. I can't provide you with an exact date but it will be coming out probably around mid-December.

Thanks!

[saraballeri]

@VishalX , ok maybe I'll be waiting. Anyway, is there a documentation, paper or whatever that explains how the framework works in more detail? I've seen opcode, XGraph class, kernel, scheduler and more, but from code it is very difficult to understand how CHaiDNN works.

Thanks, Sara

[VishalX]

@saraballeri,

Unfortunately, there is no documentation right now on CHaiDNN framework. But if you have specific questions on something, please post them and we'll try to address them in the best way we can.

[saraballeri]

Hi @VishalX , I'm going to open a separate issue to make a question about the CHaiDNN workflow. Thanks.

[saraballeri]

Hi @VishalX, do you have any update about the release of CHaiDNN with the support for Zynq702 devices? Thank you.

Sara

Hi, While looking for the new release with support small resource. I tried to rebuild the project for ZC706, as I see the resource of this board is not totally different as compare with ZCU102, except for DSP. I finished building the "libxlnxdnn.so" with the new dsa platform of zc706 (Build CHaiDNN Hardware phase), but when it comes to an example (Alexnet, VGG), errors generated even the example has been included sds_lib.h and xi_interface.hpp.

Bwt, in my case, I need to add -lpthread and -mfpu=neon to avoid other errors. Have you tested with this?

Best Regards, TuanH

[VishalX]

Hi @tuanho27

For sds_* calls, you have to include correct sds_lib.h. Same goes for linking the sds calls. In Makefile, update the variables for aarch32. For example,

ARM_INC := $(SDx_BUILD_PATH)/target/aarch64-linux/include
to
ARM_INC := $(SDx_BUILD_PATH)/target/aarch32-linux/include

I'm not sure of the correct directory name, please check in sdx installation folders.

[tuanho27]

Hi @VishalX ,

Thank you for your reply. I already adjusted the link to SDx for ARM-32 before execute make, you can see it in my log file above. I met this error before with SDSoC GUI env for another pj... and fixed this. (I/home/tuanho/Xilinx_SDSoC/SDx/2018.2/target/aarch32-linux/include -)

That the reason makes me confused. I thought it has to run smoothly this step and the error will be generated in the implementing step for over resource (if any). Still don't know the reason, and besides all API functions have errors too even the interface header added. However, I will check to find out if the Makefile for ARM-32 already checked by your work.

Regards,

Hi,

Well, after wandering around and tried to fix the errors. I re-checkout the repo again and rebuild from the beginning, include new platform (*.dsa), this time fortunately by somehow, the build process of example works. That's surprise. By now I can test some pre-trained models successfully :) Besides, because when I tried to put all layers (conv, deconv, pool) to HW, the resource is over as I guess. I then used the option DIET_CHAI_Z = 1, everything works now, I attached some images

Over resource on ZC706:

Build successful with DIET_CHAI_Z = 1

Thank your team for great work , Regards,

I get that the resources on zedboard are not sufficient. Is there any way out ?

Hi @tuanho27 thanks for the comment. I am also using zc706 to build the network in sdx. I am facing errors such as ERROR: [DMAnalysis 83-4416] Specified sys_port: ps_e_S_AXI_HP0_FPD for in1 cannot be found in the platform!
