Found an unsupported target: EDPA_1_2 when executing DLA on G720

Hi, I am trying to execute a DLA model compiled for MDLA5.3 on G720 pre-built pre-release image sourced from https://download.mediatek.com/aiot/download/prebuilt/v25.1-pr/scarthgap_k6.6_v25.1_genio-720-evk_private_250930084409_dev.tar.gz i can compile the model to DLA using ncc-tflite sourced from NP8 downloads for mt8189 I use the below command to convert the tflite model to DLA ncc-tflite –arch=mdla5.3 </path/to/model.tflite> -o </path/to/model.dla> –relax-fp32 –opt=3 this generates the D…

I know MDLA is the deep learning accelerator by MTK, but
what does EDPA stard for? What is its function?

Hi Peter,

Genio520/720 doesn’t have the EDPA target, but EDMA. They do the same function during AI inference.

You can find a detailed explanation regarding your question in this post:

What is EDMA(EDPA)? what is it's function?

Thank you for your question regarding the role and function of EDMA when running models on the NPU. EDMA stands for “Enhanced Direct Memory Access.” Within MediaTek NPUs (such as those incorporating MDLA, the MediaTek Deep Learning Accelerator), EDMA is a hardware engine responsible for efficient data movement between memory and core computational units. EDMA Functions and Capabilities Primary Role: EDMA handles high-speed data transfers, acting as a “data mover” within the NPU architectur…

Feel free to let me know if you have any more questions after reading through it.
