Circular Output Buffer - 2025.2 English - UG1603

void k1(input_stream<int32> *in0, output_circular_buffer<int32, adf::extents<OUTPUT_SAMPLE_SIZE>> & out0)
{
    auto out0Iter = aie::begin_circular(out0);
    for (int ind = 0; ind < OUTPUT_SAMPLE_SIZE; ++ind)
    {
        *out0Iter++ = readincr(in0);
    }
}

Important: When kernels are located on the same tile in the AI Engine, you can apply memory addressing optimizations. Some restrictions might arise due to this optimization. For instance, if K1 and K2 are situated in the same tile and are connected through an output-to-input buffer, they must use the same type of addressing. This means they can either opt for linear or circular addressing, but they cannot have a mixture of both.

This limitation is not applicable to x86 simulation because it only emulates functional aspects of AI Engine tiles and memory. For more details on x86 simulation models, see Limitations in AI Engine Tools and Flows User Guide (UG1076).
