DRP-AI Translator
DRP-AI Reserved Memory
The DRP-AI Reserved memory is required for AI Inference processing. The memory areas is where the AI model binary, weights, bias, parameters, activations, and configuration files are located.
DRP V5.00 to v7.00
The latest version of the DRP library moved the reserved memory start address. Due to this change DRP-AI Applications that worked on DRP version 5.00 ( BSP v1.00 ) will result in errors with the latest DRP-AI drivers.
To resolve the issue regenerate the DRP-AI models using the DRP-Translator. First modify the Address YAML configuration file to point to the new reserved memory.
DRP-AI Translator Address Map YAML
The configuration file only requires the two modifications
Step 1) Use the following template below
name: "ALL" addr: 0x80000000 lst_elemsp: - { name: "data_in"} - { name: "data"} - { name: "data_out"} - { name: "work"} - { name: "weight"} - { name: "drp_config"} - { name: "drp_param"} - { name: "desc_aimac"} - { name: "desc_drp"}
Step 2) Only the Address to the DRP-AI Reserved Memory needs to be set. For RZV2L this would be
addr: 0x70000000
Step 3) After the DRP-AI Translator is run a new address yaml and text files is generated. Below is an example generated ymal for TinyYoloV2..
name: ALL addr: 0x7000_0000 size: 0x30f_68c0 lst_elemsp: - { name: data_in, addr: 0x7000_0000, size: 0x9_6000 } - { name: data, addr: 0x7009_6000, size: 0x103_9c16 } - { name: data_out, addr: 0x710c_fc40, size: 0x1_4a14 } - { name: work, addr: 0x710e_4680, size: 0xd000 } - { name: weight, addr: 0x710f_1680, size: 0x1e4_280c } - { name: drp_config, addr: 0x72f3_3ec0, size: 0x1a_6280 } - { name: drp_param, addr: 0x730d_a140, size: 0x270 } - { name: desc_aimac, addr: 0x730d_a3c0, size: 0x1_c1e0 } - { name: desc_drp, addr: 0x730f_65c0, size: 0x300 }
