TDA2: network speed problem

user3792633

Part Number: TDA2

HI，

i am using tda2x/PROCESSOR_SDK_VISION_03_06_00_00.After install and build,starting run the usecase--"1CH VIP Capture + Network TX".

oh,my evm board ip address is static --192.168.1.200,and pc side is 192.168.1.201.And network cable was connected to EVM board side P5 port.

And then,running the command in windows cmd terminal.

"network_rx --ipaddr --target_ip 192.168.1.200 --host_ip 192.168.1.201 --port 29172 -usetfdtp --files 20190214_001.yuv"

my problem is the speed of network.Less than 1280*720 30fps.just about 10fps.

How to improve the speed of network?thank you.

Hi @user3792633 ,

from VisionSDK_UserGuide_NetworkTools.pdf:

IMPORTANT NOTE:

When sending RAW/YUV frames

When NDK runs on M4 CPU, one can achieve a data rate of about 2 MB/s (16Mbps)

When NDK runs on A15 CPU (TDA2x or TDA2px), one can achieve a data rate of about 60 MB/s (480Mbps)

Can you make sure NDK runs on A15 core? You should have NDK_PROC_TO_USE=a15_0 in the build config you use.

Regards,

Yordan

hi Yordan,

I am sure Ndk runs on A15 core now.Here have two pics about config.

Hi,

While the transmission is going on, please check your network speed in system monitor. To match your requirement, approximately 422 Mbps network speed is required. This is theoretically possible, but this can depend on your network bandwidth. But since you are using static IP, and you're connected to the PC directly from the EVM, I wonder what could go wrong. Please let me know if the network speed you observe is sufficient for the required data transfer. Meanwhile I'll try to replicate this on my side.

Anand

Hi Anand,
Network speed is 64Mbps when the usecase in running.Not able to achieve 422Mbps.

Hi Jeremy,

I suspect that you won't be getting the desired FPS since you're working with raw data. You can try with encoding and see if you're getting the desired FPS. Since you're using static IP, network speed issues shouldn't come up. Just to get a closure on that, please check the UART console log of vision sdk and see if your connection is 1000Mbps.

Anand
