TDA4VM: Slowdown when using five cameras and TIDL

gordon huang

Part Number: TDA4VM

Hello,

I'm having a problem where it seems there is a slowdown in processing when I'm running cameras and TIDL in parallel. I'm using five D3RCM imx390 cameras on EVM board with fusion board. I'm using SDK 7.01.

My application has a two modes, first mode is cameras feeding to TIDL, 2nd mode is images are sent over network to TIDL. In both modes the only difference is the source of the images and the related nodes (capture nodes vs network node), the TIDL node and everything after (pre processing, post processing, display nodes) are all identical.

When I run the network mode, I see the TIDL processing time is around 90 ms. When I'm running the camera mode it increases to 122 ms. I also ran against the multi cam app and found the VISS bandwidth also decreases from 318 MP/s to 286 MP/s, and I measured camera frame rate drops from 30 fps to 27 fps (which match the MP/s numbers, ie 1936*1096*30*5=318MP/s). I'm guessing the VISS and C7x are struggling to get enough memory bandwidth to run "full speed".

So a few questions. Is there a way to allocate more bandwidth to each HW unit? I'm not using all the HW units, like C6x or LDC so if reallocation is possible it may help. What is the max memory bandwidth on the EVM? I tried a few tests but it seems it maxes out around 5500 MB/s (~25%). How can I reach higher utilization numbers? Is there a way to measure memory bandwidth usage of the A72 CPU?

I added a monitor function to call appPerfStatsPrintAll() roughly every 10 sec, here is what I'm seeing:

Hi,

Do you see any issue when you run less number of channels, lets say 3 or 4 channels?

capture and VISS will definitely add to the total BW, but we need to first understand the usecase, then we can try to optimize it.

Can you please check/contact your Local support for the further support?

Regards,

Brijesh

Hi,

With 3 or 4 cameras the application runs fine, with the expected camera fps and TIDL processing time.

Hi gordon huang,

Could you please share complete performance stats for 5 channel? Would like to see which component is slowing down the entire chain.

Regards,

Brijesh

What do you mean by complete performance stats? Which APIs to get that information?

Please press 'p' on the console and share the log output.

Rgds,

Hi,

My application doesn't have command line interface, but I did add the same calls used in the example program 'p'. Also, in my app there are 3 TIOVX graphs, so the output is somewhat duplicated:

Hi gordon,

but according to these stats, the graph is is running at correct fps, ie 30fps. Do you expect higher fps in this case? or are you running 5 camera for this stats?

Hi,

This is running the 5 camera mode. I'm not sure how the TI lib is calculating the FPS, but when I measure the rate from application side it is not right. Maybe it's only counting frames it processes and not what it's skipping? Looking at the data for HWA,

HWA: VISS: LOAD = 54.68 % ( 521 MP/s )

54.78% * 521 = 285.4 MP/s

1936 (width) * 1096 (height) * 5 (cam) * N fps = 285.4 MP/s

N = 26.9 FPS

This FPS number matches what the frame rate I receive on my application side, which is 27 FPS. Also, check the DSP_C7-1 TIDL numbers, they have increased by 40%. They are both running the same models.

PERF: TIVX: avg = 16381 usecs, min/max = 14852 / 44038 usecs, #executions = 500

PERF: TIVX: avg = 23274 usecs, min/max = 18454 / 39954 usecs, #executions = 500

The slowdown in TIDL is more critical for me, since we can't run entire pipeline at 27 or 30 fps anyway. The TIDL processing is the bottleneck for entire pipeline, I'd like to at least keep the TIDL processing time as short as possible.

Hi,

So I reran test on the D3 RVP-TDA4VM board, and found some different results. On that board, the 5 camera setup runs fine without any TIDL slow down. The frame rate I measured was around 28.5 FPS.

Looking at the statistics results, it looks like both DDR bandwidth and VISS are both higher than on TI EVM board. I'm wondering, maybe D3 has different DDR config to allow higher throughput? Why does the VISS have higher MP/s value (574 vs 521)?

Since our application runs as expected on D3, this issue isn't so critical, but it would be nice to know why there is a difference and how to configure both boards to behave similarly.

Camera mode on D3 board:
