Detailed Description

Structure compiled into the command buffer then passed to some CPU op extension functions.

Note

To maintain compatibility with simulator builds, the parameters are in elements of NRF_AXON_PLATFORM_BITWIDTH_UNSIGNED_TYPE. This is 64bits on the simulator, 32bits on Nordic MCUs. By organizing this as a series of unions, the upper 32bits of the parameters remain 0s unless the argument is a pointer.

Op Extension Base 2 profile arguments. The following conditions must be met for an op extension to use this structure to pass its parameters. (If the conditions aren't met, a new structure needs to be defined.)

• A single input vector.
• input and output dimensions are not the same.
• no quantization involved in the oepration.
