-To make use of a neural network model that is optimized for this configuration, the linker script for the target

+For *Ethos-U55* NPU, the system SRAM can also be used to store the neural network model along with the `tensor arena`.
+Vela supports optimizing the model for this configuration with its `Sram_Only` memory mode.
+Although the Vela settings for this configurations suggests that only AXI0 bus is used, when compiling the model
+a warning is generated, for example:
+
+```log
+vela \
+  --accelerator-config=ethos-u55-128 \
+  --optimise Performance \
+  --config scripts/vela/default_vela.ini
+  --memory-mode=Sram_Only
+  --system-config=Ethos_U55_High_End_Embedded
+  ds_cnn_clustered_int8.tflite
+
+Info: Changing const_mem_area from Sram to OnChipFlash. This will use the same characteristics as Sram.
+```
+
+This means that the  neural network model is always placed in the flash region. In this case, timing adapters for the
+AXI buses are set the same values to mimic both bandwidth and latency characteristics of a SRAM memory device.
+See [Ethos-U55 NPU timing adapter default configuration](../../scripts/cmake/timing_adapter/ta_config_u55_high_end.cmake).
